You can do that, but what level of false positives are you willing to accept?
How often are willing to have your car perform an emergency stop for an overhead sign? How safe is it to have your car brake aggressively in a middle of the highway for nothing?
- gambiting 6y agoI don't know why you keep mentioning the overhead signs? The anti-collision radars that are mandated in every new car are mounted on the bonnet level, they won't react to an overhead sign. And yeah, emergency braking in the middle of the highway is not safe at all, but seeing as literally all new cars have to have that system and we're not seeing people randomly braking in the middle of the motorway for no reason I can only guess it's fine. Besides, the system doesn't start braking if you're actively applying throttle, it will start beeping at you but it doesn't start braking until you lift your foot off the gas.
- oldgradstudent 6y agoBecause overhead signs were mentioned as one of common sources of radar false positives during the reporting about the 2016 Tesla crash.

But we definitely do. https://www.cbsnews.com/news/automatic-emergency-braking-in-cars-will-be-standard-by-2022-but-false-activations-still-a-concern/ https://www.cbsnews.com/news/automatic-emergency-braking-in-... The price we pay for having relatively few false positives is a high false negative rate. For example, a Tesla won't stop for an overturned truck or the pedestrian standing next to it.
