SIAM: the fix for the SMIDSY

[ZeroIndex]

Hey,

Not sure if this'll be a repost... but even if it is, I just think it needs to be posted again.

I found it good to watch, unfortunately, I've forgotten what SIAM means already. But the weaving motion is instilled in my mind.

In the pic below, is a car coming towards me with a bike in front of it. Without the headlight on the rider would be hard to see. I could see him because I seem to zoom in on any motorbike. Sort of demonstrates what the video is pointing out about the size of a bike against the background.

SMIDSY Identification Avoidance Manoeuvre....
Yup, great watch.
It is something a mate of mine, who spends a lot of his life in large aircraft, suggested to me that we should do.

"because drivers are inattentive , it's our responsibility..."

Sad, but true. The majority of drivers are unable to 'see' anything smaller than another car. Actually, many don't seem capable of even that...

[Big Dog]

Problem is not so much size as perceived threat.

I don't know about you but I don't always see dogs. I sure as shit see even the smallest ones lurking on the side of the road. Especially if they have their hackles up.

IMHO, based purely on my own observation and 20+ years experience including two SMIDSY events:
ATGATT riders get a wider berth from car drivers.
Riders with something standout about their appearance such as Fluro vests before every road crew and his dog had one or a Mohawk for your helmet. Fluro vests seem to be less effective these days. But that is not fact, just this riders opinion.
White bikes get a wider berth
Red and grey bikes are difficult to see at sunrise or sunset.
Black bikes are difficult to see at night.
Grey bikes become almost invisible in a concrete landscape.

None of this matters unless you are on point taking responsibility for yourself.
We can't have a fleet of bikes where we choose the right colour for the current lighting and intended destination but we can:
ride sober
ride alert
Ride defensive
Make eye contact
Give yourself as big a profile as possible ( sit up if your in a full tuck and you suspect someone has not seen you)
Don't be afraid to use your horn
move about the lane when there is a likelihood we are less visible
make sure all our lights and signals work correctly
Make sure we use signals etc
Consider changing our signals if they are difficult to see from 30m ( put your indicator on and walk 30-40 paces away, can you see them? If not can a driver in a cage? Micro indicators are not for every bike and big stock indicators are often not as visible as they might seem.)

Should we be giving cars a free pass? F@&k no! Should we do everything in our power to see our families again? Hell yeah!

Make eye contact

Possibly one of the most under-rated safety actions a rider can make. Once you have eye contact with a driver, it would require a deliberate action for that driver to pull out on you. If you can't make eye contact, you know to be especially aware that this driver may not have seen you. Similarly, just because you have a 'connection' witht he driver at the front of a queue, know that the driver behind may not have the same awareness. I've seen and heard of many accidents where the first car cleanly and carefully manoeveured, only for the second car to cause an accident. Many drivers tailgate, working on a 'room for one more' idea, and often there isn't.

Some drivers simply won't see you regardless of what you do. Sorry, but that's how it is. All the fluoro and lights in the world aren't going to change this. It is a riders responsibility to themselves to know this, be aware of when this happens, and act appropriately.

I helped on a CBT course while back in the UK and had to repeatedly tell new riders that it doesn't matter what the highway code or the law says, or how obviously and definitively 'in the right' a road user is, the bigger vehicle will always win. If you're walking, on a bicycle, or a motorbike and hit or are hit by a car, you will come off worse. Nature doesn't care if the traffic lights are red, if your indicator was on, or anything else.

Please - have fun. But ride carefully.

And if you have a tinted visor, you can just stick your left-hand middle finger out in the general direction of the driver, if they start to pull out and then notice you :laugh:

Guess I will be having an interesting talk with one of them sometime soon then and just how poorly trained on motorcycling they are. Wonder how they would take it if I suggest they take an ACC ride forever course, think they might find it interesting? :lol:

I use the weave especially when riding behind a mate as I have noticed many drivers seem to think bikes are either in massive groups or singles. I also do it a lot to break the boredom. If nothing else the weave will cause your headlight to vary and humans seem to have an affinity for noticing moving light.

Beware the eye contact, they might be looking straight through you and you have to fix your vision on the driver, you may not see the wheels moving. That said, people do notice mean others are looking at them, I have used this to get bar maids attention before :innocent:, so that may help the driver notice you.

[eldog]

I have been doing this for a while automatically, but only to keep alert, more handling practise (I don't ride as often as I should) and get the tyres warmer.

The ACC Bronze course - suggested doing this weaving as well

Now I will try and make it an automatic response when I am riding near any intersections it will only be a small weave, otherwise might be interpreted as a prep for turning :gob:

Had a narrow SMIDSY escape last week, car turned on a red (I had the green arrow) :crazy: it was close.

[eldog]

I really wanted a water cannon mounted on the front of the bike the other day when a driver turned on a red right in front of me:facepalm: didn't even realise I was there.

got to fit the sebel and get some loud pipes and more lights.

the high vis just useless when they don't even look, just drove upto the lights and turned

I had something similar on the Mighty Scorpio, but nowhere near as many lights

I like the flashing lights they do draw attention.

However I found I had too much light when I went from full to dip esp in the countryside

Too much light in the middle of the bike also caused drivers to still not see me (I looked too far away from them to be a threat)
Once I spread the lights apart this made a major difference, even though its a small bike.

good job - make yourself visible and to enhance the usually poor manufacturer lighting system.
The Scorpio has quite a good standard light pattern which surprises most.

I used to follow a Suzuki GSX650 a lot and noticed that the light was poor for lighting up corners when slowing down into them, the light pattern was concentrated forward and lacked any wide angle spread so the slow speed curbs would 'disappear' from the riders vision

just wondered how you got on with the WOF

[ZeroIndex]

I normally just run them as solid beam... Really adds width to the already wide ZX14. My friend keeps thinking a truck is chasing him :)

Hi Anne,
In my experience, being a good biker, will automatically make you a good driver, and much better at spotting hazards.. But being a good driver, doesn't automatically make you a good biker, or good at hazard awareness.

Could not be fecked watching the video but I have been moving to catch a drivers attention for a long time. Not a weave as such, I change position and speed in my lane to be more noticeable and also to give me more space should they still pull out. Seems to be effective and I think quite a few drivers realise why I'm moving. Had the thumbs up from truckies before when we have made ourselves more visible and regularly see drivers rolling into a junction with quick glances focus on me and stop, often well over the line.

I do believe that training and practice on a bike improves observation. Discussing this with the instructor on a pro rider gold course he suggested a mental running commentary to improve the skill and have an ongoing scale of risk, he is a Federale and no doubt that is the reason why it is used in training.
I thought I was pretty good with observation but the commentary has improved me. I'm spotting things bloody miles away now and more proactive about what I can't see. I guess it trains the brain to stop filling in the gaps, the main reason for smidsy, and actually look and register what is going on.

Running commentary in my head - Been trying to do that, reduces the amount of other stuff interfering with the ride and the inattention that I have been guilty of.
I am improving on that score but its quite difficult, practise will see it improve. Its helping me at other times too, only trouble is I am dealing with lots of interruptions all the time, focussing can be a strain.
I need to develop a method so it becomes automatic - spend too long describing stuff, need to sort a sort of shorthand for items
like telephone pole=pole, descriptive terms for street furniture etc

Kinda distracted me when I started, too. I tried to do it literally as a commentary like you see on the telly but I realised that most of the stuff was not really a hazard once it's registered. I sort of file or discard what I see. Much easier. What I have gained since that wee revelation is looking as far ahead as possible, yeah, we all do that I know, but I mean really seeing as far as I can and registering it. On my daily commute there are stretches of road that I can see a long way through, dropping into & out of a valley, a straight going into a windy uphill etc and my wee "check list" has got me seeing the furthest piece of road where it disappears and everything in between. Twice in the last week I have clocked cyclists just vanishing around the corner at this point giving me reason to be cautious maybe a Km or more from where I spotted them, just wee specks disappearing. The road in between has a clean bill of health sort of so I'm thinking further ahead. I don't think I would have been seeing such detail a couple of years ago, more interested in the line for the next corner. It's manifested in all sorts of ways but basically one thing leads to another to figure out what lies ahead and what I should be doing about it.
I guess the "hazard scale" and commentary have helped me think further ahead and increased pro active riding.

[ZeroIndex]

At my stage in riding, it's fairly automatic, everything is in two categories. 1). is it mobile (people, vehicles, animals) 2). is it inanimate (parked vehicles, gravel, roadworks, etc)... Mobile stuff, take notice of, be prepared to slow down, stop or look for escapes. 2). Inanimate stuff, do I need to change my road position due to part of my lane being taken up, had the road surface changed at the beginning of a corner etc

Cool, I also look out for driveways, farm gates. Countless the number of times I have seen farmers plough out of a field across or turn left onto a road, along with any animals that might stray.

Country roads - harder to see, sometimes I see the dust kicked up in the distance. Goats, Sheep etc appear from ditches which can be fun. but they tend to turn away and pretend if they don't see me, they wont get hit.

Ducks and opposums are my worst enemy at the mo, they turn around and cross in front LOL now I never assume they are running away :innocent: - assume nothing is becoming my motto

fair enough and perhaps a good way of breaking stuff down

esp the has the road surface changed at the beginning of a corner, I was victim to change in road condition midway through a corner, which I couldn't see.

I look at lot more at the road condition when I ride. As per the old ad - Everything is riding on your tyres

[Frodo]

Just seen this video and I beg to differ.

I've ridden close to 200,000km since I got back into riding ten years ago. Been in lots of situations where cars have pulled out like on that video. But I had a SMIDSY three weeks ago. This occurred literally in the split second when the ute towing a double axle trailer in front of me turned left and a silver Corolla saw a gap and darted across SH1. The road was greasy and I over-braked, went down and slid across the road. Bike is easily repaired and I'm now just about 100%. A good reminder. By the way, the normal gap that I leave in front to give me time to avoid SMIDSY's like that was filled by the ute who aggressively filled the gap from an intersection just up the road.

Weaving would not have been possible in that situation. But I disagree with the approach in principle. If you have enough time to weave, then you have enough time to slow down and move to the right of your lane. If anything, weaving will reduce your traction and ability to avoid a collision. You may weave just when a car behind is overtaking (I note the recommendation to look behind, that means you aretaking your eyes off the primary hazard). And there is no guarantee that they will see you.

So I disagree with SIAM. I propose THAI.

So my rules are:
- Travel at a speed where you can stop in time (or at least scrub off most of the speed).
- Look for Hazards
- Assume that the Corolla, Massey-Ferguson, border collie, etc will move into your path
- Initiate braking

you are taking the weaving to far..its not a weave from side to side in a violent way,its not much more than a repostioning in the lane,but the same move back and forth ,the sideways movement may be more visible to the smidser than path that shows no sideways movement

Yep, it's about creating just enough movement that your lights aren't "stationary" from a distance.

I've definitely found my foglights I installed on the ZX14 have definitely helped in regards to being seen. It also helps create a wider profile for my bike.

Reminded me about 'Close Encounters of 3rd Kind' but I like it :niceone:

Its really dark in the Waikato at night, so used to AKL street lights

only problem with toooo much light is

blinding yourself when you goto dip and up again - fatigue
adjustment of the light, put them where you want to see.
My bike has a nice light but doesn't show much of the road when cornering, ie the sides of the road.
I have more lights to be fitted that will help like yours

as usual just a small amount of weave/jiggle is enough :shutup: to attract attention

the extra width makes it easier for the onlooker to judge your approach speed,but they may still be fooled into thinking you are a strange car,further away than you actually are.

You never know :p ...I've always looked at it like this: single or dual headlight that is close together gives the impression of "distant car"... wide lights (like the fog lights I have mounted on my crash pegs) give the impression of car at actual distance with extra auxiliary lighting. When I throw on hi-beam, it truly is amazing how much road gets lit up. Since installing the fog lights, I am yet to have any cars make any stupid moves. I managed to get two nights (last night and tonight) of back-road late night riding in... lots of fun.

I agree that the wide set lights are better than single,but the are narrower than the average car

wtf is he talking about the background movement relative to the car?

Is he just saying that if the car is moving then he's in a SMIDSY situation?

I personally think if the car is moving it's a bit too late to go larking all over the road, even if the driver does see you he's only going to jump on the brakes and block the lane. I think you're best to start looking for escape routes.

I've often approached an intersection with a gut feeling that a car giving way isn't aware of me, and wondered how to alert them. I worry that flashing my high beam might indicate "GO!" to them, tooting my horn from the range I have in mind seems ineffective, staring them straight in the eye seems to work (sometimes you get stink eye back - fuck 'em), but you compromise the rest of your situational awareness. Weaving seems nice, but I worry that it might compromise my road position if I have to make an evasive maneuver.

[eldog]

Weaving.

Only a small weave so you create movement relative to the car/surrounding behind you.

Think of it as if you are in/on the oncoming vehicle and you are trying to see whats ahead when you turn.

A motorcycle and its headlight only show a small shilloette when at a far distance and approximately the same when closer. Often if a car is behind the motorcycle then it may appear as part of the 'vehicle' coming.

Creating a small wiggle will create movement and alert the driver that some other vehicle is there.
On my bike I put small LED positioning lights which modulate. I put them up high and wide to make the bike appear bigger and closer than it really is. A triangle pattern of lights makes it just a different shape - also helps.

Small weave 50mm not a whole lane movement.
