    Pondered it.

    Everyone thinks they are above average.

    Did you do high school maths? That's not how averages work. If everyone was above average, the average would be higher. And it's not.

    Still, I'm thinking that sarcasm emoji might have been useful.

    Did you pass high school maths? You're not doing much to help the stereotype. His brief and witty statement is exactly how averages work. Maybe it's reading comprehension you need work on.
    Don't you look at my accountant.
    He's the only one I've got.

    So, if your typical speedo reads 50, you are typically doing 45/46.

    I've had bikes that are reading 70 when I am actually doing 50. Gotta love Italian scooters.

    So, if a popo with a radar checks you at 56 , your typical speedo would have been reading 60 or 61 at the time that speed was locked.

    So speedo error almost always causes you to go slower, not faster.

    The primary exception is those vehicles fitted with wheels larger than standard e.g. your Hilux Surf with penis-extension wheels.

    So, the speedo error argument is an easy one to throw out, but is almost exclusively moot.

    But hey, never let facts stand in the way of a good old whinge.
    Not always, the speedo on my wife's work car is almost spot on. It took 2 speed camera tickets before we figured that out...

    On the other hand, my car reads high by 5 km/h consistently from 50 to 100 km/h. Great feature, I've only had one speeding ticket, which was from a camera for 6 over.

    It is always worth checking the speedo when you get a new vehicle.

    The speedo on my Ducati read 30kph slow. I'm still pleased I discovered that before an officer of the law informed me. An indicated 100 was 130 and since I rarely rode at 100 anyway I could have easily been walking. Bloody Italian electrics.

    A mate bought a new A7 350 Kawasaki in about 1967 and was boasting how fast it was reading on our test strip..... We found the speedo was 20 MPH FAST !!
    It was way faster than our T20's and YDS3's but not that fast !

    Lucky for you pritch !!

    From my experience, it's not the vast majority. But it's easy enough to check using a GPS speedo app.

    How many vehicles have you tested?

    Quite a few, I used to check rental car speedos if I was doing a decent drive. Most read high but not "the vast majority".

    It's common in international law (including NZ, Europe, Australia) that speedos must not read below true speed or above by more than 10% + 4kmh, so for a true speed of 100km/h the speedo can read no less than 100km/h and no more than 114kmh. It's well known and accepted that the vast majority read over true speed for that very law.

    Yes, but some are much closer to being accurate than others. It is definitely worth checking your speedo accuracy if you want to avoid speeding tickets.

    All the German cars at my place - spot on give or take tyre wear.
    Peugeot - about 2k optimistic on new tyres.
    Fiat - 10k slower than actual speed, that one had me swearing at all the slow drivers on the road
    Every Japanese car I've bothered to check - pretty consistent 5km faster than actual, it's almost like they put the needle on offset by that much on purpose.

    Really should stick the gps on the motorcycles, and see where they sit.

    Unless you really luck into getting the road to yourself, anywhere on Banks Peninsula, dropping the speed limit will make less difference to your trip time than gran in her RAV4 out for a nice drive in the country.

    Guzzi Griso Took a jaunt to Aka

    I don't head to Akaroa hardly ever. Living North Caterbury. Getting across town AGH.

    But had to make a journey before the limits were changed. Not that I went GP speeds.
    I didn't want to visit my GP or worse case the ER
    But below is a video of that ride.

    Lovely spring day here today. Had some free time this afternoon and perfect weather to ride a motorbike. Fired up the M1100 and though I would cruise out to Little River. Saw some poor bastard paying some road tax in Tai Tapu and then got onto the open road. The very well maintained, lots of flowing corners, wide, well signposted flat road out to Little River. Speed limit 80kph. There were a couple of people on boat anchor cruisers and I though I would stay behind them so I didnt get pinged.

    I turned off at the black tulip and came home. Its fucked.

    And they want to make 80 the default limit on the King's highways? Fuck that.

    I saw some people out on a Honda Grom and some sort of mini bike. They would have been having 10X the fun I was. 100X even.

    When's the next trackday and shall I buy a boat anchor?

    The entire economy of Little River and Akaroa will be fucked if it doesnt get my bi-weekly long black and ham roll. And it won't. Thats the real cost of this Stalinist bullshit.
    I thought elections were decided by angry posts on social media. - F5 Dave

    It's going to be interesting to see if the new Mayor will have any effect on the speed limit lowering.

    He's dead right on one thing he's said already - got to get more people into the central city so making it harder for motorists doesn't work.

    I'm beginning to suspect that to have any fun out of motorcycling now, I'll have to restart riding vintage bikes as daily transport.
    Something on which 100kph is an exciting adventure into the limits of handling and brakes.
