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.
It's almost as if we need a nationwide GPS driven speed limit detection system, rather than relying on some crappy cameras.
That way manual drivers can be warned if they're exceeding the limit as well.
Even nationwide GPS speed detection isn't flawless. What if an accident happens or for road works, then a temporary speed reduction can be applied. The autonomous driving system must be able to detect those situations and handle them gracefully. But also coming out of that temporary speed restricted zone. What if the car doesn't detect the end of the zone? Then the autonomous vehicle can drive dangerously slow until the next sign.
You could certainly have both systems in place, with it always picking the lowest.
But you do want to avoid daft things, like seeing a parked lorry with "I'm speed to limited to 50" written on it, with the 50 in a red circle, and the car goes "50? Brilliant!" and zooms off past a school.
