Speedometer Accuracy?

Nah it's a pretty common issue - Toyota confirmed to me that the YR is out by about 6% .. But mine is out between 6.5-8% depending on the GPS I use.

Odd safety feature, considering if you sit on the speed limit per the speedo you're more inclined to be tailgated, which increases instances of road rage! I think there is something in the new design rules for Australia re: speedo errors. Though so many people use GPS these days it's easy to pick up where there is a discrepancy.

You got the tailgating thing and the Road Rage right! I've been driving faster now that I see the difference.
