Re: Important 'cause...
I hope the computer in these self-driving cars is better than the one on my Toyota.
Its road sign recognition system often detects speed limit signs down side roads and displays them as if they apply to the road I am on.
Several times it has "detected" speed signs of 80 and 90 mph in the UK.
It's best trick is to suddenly decide that all the UK speed signs are now in kph and warn me that I am going too fast. Then, after a few minutes, they are back in mph again.
Recalibrating the camera made no difference and other owners have reported the same issues.
