I dab too, there are dozens of us!

We have this in Europe for new cars, and the issue everyone expects is that cars are terrible at accurately knowing the speed limit. Current cars often can already show what they think the speed limit is, but it’s often inaccurate due to missing a sign or road crossing, or any other software/image recognition problems. Which means you’re bound to get false positives, causing drivers to turn off the warnings each time.
