Seminars for fun

[rastuscat]

I ran some seminar sessions at our Kickstart event yesterday.

Topics were

1. The quickest way to get a motorcycle licence
2. Lanes, lane splitting and filtering
3. Positioning

It never ceases to amaze me how little people actually know about the law, but who will claim to know it all.

The one I always ask a crowd is "What's the legal following distance at 50 kmh?". The answer I get is always the 2 second rule, but of course, that's not the law.

People are almost always surprised when I tell them the road code isn't the law, it's a collection of good driving/riding practices based on the written law, and a box of good ideas.

The lane splitting topic drew a wide range of questions, which makes me think there may be a need for better clarity on that.

At a sufficient distance that you can stop short of the vehicle in front. There is a stated distance, but that is the minimum without factoring in the performance of the particular vehicle you are driving, so there is more than one way to break the law.

Comes to mind as I was looking at this for an entirely unrelated reason, the land transport rule does specify the minimum distance for 50kmh but rather than answer here it's more fun for people to look at the legislation themselves, and realise that most people driving in traffic are not observing it

On unlined roads within 1/2 the distance visible. Thing that frightens me is my hill road is lined. So stop within distance visible.

But parked cars mean it is impossible to not travel some distance on the wrong side of the road. You can meet someone coming opposing you and hope they are following the 1/2 rule despite being laned.

It's safer on a bike clinging the side.

In my car i regularly drag off following cars around the right hand hairpin as I take a better line but I then come to a combination of left hand bends against a bank and car chicanes and they invariably catch up to me as they travel around as if they will never meet a mamal puffing his bicycle home from his resolution to get fit or indeed a car crossing over to avoid parked car..
I guess they can see the future, or at least through obstacles. Hoping for this superpower to kick in.

That sadly includes the police. The Brit Youtube drone operators strike it all the time. Both from the public and the police. It's not surprising that NZ is similar.

Actually it's not just Britain. Some people anywhere seeing something new decide it must be illegal.

In summary it's 4 metres per 10 kmh up to 36 metres at 90 kmh, then 36 fir any speed above 90.

This too. Its a different section of the Rule, but equally applicable.

[Gremlin]

... and realise that most people driving in traffic are not observing it

How else do you think we get 5 car pile ups? I don't get me started on the motorway patrol show, when the driver at fault says... I was driving, and the car in front, he suddenly stop! I have nowhere to go! Why is it my fault?

I recall a stat from the 90s when I did a short stint on Auckland Motorways, based at the Harbour Bridge office.

76% of crashes on the motorway are nose to tail. I would have thought it was higher.

bullshit, they are caused by alcohol and speed,

Is the "1 car length per 10km/h" in the road code?Thats what I recall as "the rule".In practie i try to observe the 2 second rule as a minimum

Here's the law.

5.9Stopping and following distances
(1)

A driver must not drive a vehicle in a lane marked on a road at such a speed that the driver is unable to stop in the length of the lane that is visible to the driver.
(2)

A driver must not drive a vehicle on a road that is not marked in lanes at such a speed that the driver is unable to stop in half the length of roadway that is visible to the driver.
(3)

A driver must not drive on a road a vehicle following behind another vehicle so that the driver cannot stop the driver’s vehicle short of the vehicle ahead if the vehicle ahead stops suddenly.
(4)

No driver may drive a motor vehicle on any road following behind another vehicle at a distance behind that vehicle of less than—
(a)
16 m, if his or her speed is 40 km an hour or more but less than 50 km an hour; or
(b)
20 m, if his or her speed is 50 km an hour or more but less than 60 km an hour; or
(c)
24 m, if his or her speed is 60 km an hour or more but less than 70 km an hour; or
(d)
28 m, if his or her speed is 70 km an hour or more but less than 80 km an hour; or
(e)
32 m, if his or her speed is 80 km an hour or more but less than 90 km an hour; or
(f)
36 m, if his or her speed is 90 km an hour or more.

And here's what the road code says.

https://nzta.govt.nz/roadcode/genera...owing-distance

If you apply the 2 second rule, you arenalways further back than legally required. Which is a good idea.

Everyone can tell you the 2 second rule, but few actually apply it. And it only works if you actually apply it.

Here's the law.

No driver may drive a motor vehicle on any road following behind another vehicle at a distance behind that vehicle of less than—
(a)
16 m, if his or her speed is 40 km an hour or more but less than 50 km an hour; or
(b)
20 m, if his or her speed is 50 km an hour or more but less than 60 km an hour; or
(c)
24 m, if his or her speed is 60 km an hour or more but less than 70 km an hour; or
(d)
28 m, if his or her speed is 70 km an hour or more but less than 80 km an hour; or
(e)
32 m, if his or her speed is 80 km an hour or more but less than 90 km an hour; or
(f)
36 m, if his or her speed is 90 km an hour or more..

Which clearly shows that whoever wrote the law has no actual knowledge of physics. The energy needed to be dissipated goes up with the square of the speed. The 'law' is for a linear increase.

It was stupid when I got my license in 1972 (although memory tells me that it was measured in 'car lengths' then) and it's still stupid now.

And not just the LTA but also the law in general.

It's pretty hard to every cop to know every law in detail. Those who specalise into road policing often become specialists.

Those who just rotate through road policing as part of career progression often think they know it all, but actually don't.

I’ve been hit from behind three times while operating truck, motorbike and car. Each time following distance wasn’t an issue, it was failing to pay attention. In fact I wish they were actually tailgating me as the speed differential on impact would have been less.
Yes a lot of what you mention is caused by no stopping distance but it’s wasted if the driver is paying attention to start with
