Michael's V8Y62

[V8Y62]

Fwiw I'm pretty sure the Australian car standards state vehicles must read a minimum of 6% over the speed they are travelling? I guess Nissan just took the y62 a few percent further?

No it doesn't it states the allowable difference between speedo and road speed + a fudge figure. The formula for ADR 18 (as of 2006) for our vehicles is 0 ≤ (V1 – V2) ≤ 0.1 V2 + 4 km/h. V1 is speedo speed, V2 is actual speed. So 0 ≤ (100 – 91) ≤ 0.1 91 + 4 km/h can be up to 13 kmh (0.1 91 + 4 = 13.1) which is ridiculous (infact teh entire formula is ridiculous as it encourages inaccuracy +4 kmh more which adds even more inaccuracy). We are given 5% leeway on speeding tickets (go higher than 42kmh in a school zone in NSW and you are in trouble) yet we can be going as low as 86.9 kmh when our speedo reads 100 kmh.

In all honesty I've never owned a vehicle that is more than 5 kmh out and that's why it was so noticable to me and why I'm researching GPS HUDs.
