Not surprising to anyone that ever driven a Tesla, or other brand car really. The speed sign detection only works about 90% of the time, which is fine if you are in control, but for self driving? Had the same with BMW, Mercedes, Renault, Honda. None of the cars I've driven over the past years were close to 100% correct with reading signage.
I've noticed that, too.
The speed signage is nice when the car picks it up, but I'd call mine 80% accurate. Imperfect, but fine for a driver assist, I know not to rely on it.
Crazy move to put it in a 99.9999%-accuracy-required design.
Google maps knows the speed limit of most roads, why can't that be used?
Not super reliable, one road near me is 25mph and google says it's 65mph.
Oh, well that answered that question. Get your shit together tech bros
Because the "Google thought so" approach is legally problematic.
Ah, that makes sense.
