Seymour said the car in front of him was driving erratically, speeding up and slowing down in the right lane.

    It looks like a Toyota, they’re pretty notorious for having inaccurate speedometers. He was probably doing closer to 95.

      I’ve had a few toyotas and driven many more and with the roadside speed signs they don’t seem that far off. I find pretty much all cars over read by about 4kph, give or take a couple, putting the filmer’s speed at a bit over 100.

      It does seem like the filmer and the one in front are camping in the right lane when they shouldn’t be.

      I guess I just don’t think this is a zinger since this doesn’t even register on the scale for me among all the driving craziness I’ve seen.

        I’ve seen almost 10% out, checked against a GPS app on my phone, so almost 110 on the speedo to travel at 100 actual.

        I’ve actually fitted tyres a size bigger than recommended to get a speedo to read accurately.

          I’m not sure what standard this refers to, but I dug up this article I remember reading previously (it doesn’t appear to be published on the site anymore)

          The applicable standard for many vehicles sold in NZ is a European standard that specifies that speedometers must not indicate a speed less than the vehicle’s true speed, or a speed greater than the vehicle’s true speed by an amount of more than 10 percent plus 4 km/h.

          If true, that means a speedo is considered legally accurate if it says 114 when you’re driving 100, which is a pretty massive difference.

          Bigger tyres is a nice workaround, both our cars over read by 4kph so I just do the maths.

            A speedometer that far out is effectively useless, and if I bought a vehicle like that I’d take it up with the dealer.

            So yes, Seymour might not have even been speeding.

              This is one of my pet peeves; this is not the 1950’s; we can make speedometers accurate to within 3%…this margin would account for all the vagaries of tire pressure etc.

              Our newest car; pleasantly has a very accurate speedo…

                Modern vehicles have GPS calibrated speedometers, and are often dead on. But for an electronic speedo, there’s no excuse for more than a few percent.
