Drivers Tend To Kill Pedestrians At Night. Thermal Imaging May Help.::Pedestrian automatic emergency braking (AEB), which may become mandatory on U.S. cars in the future, tends to not perform well in the dark.

Every newer car I've driven so far has had one installed and enabled by default. These things work fairly poorly, especially in snowier conditions (in my experience).

Yeah, iirc it became or about to become a requirement in EU. But I was not aware that it has false positives like that, that just makes ppl not use them.

However these are indeed two different things - one is emergency braking (on by default, breaking only, radar, camera of radio-wave sensors), the other one just for comfort that you can keep both pedals alone and it's an extension of crouse control (radar based, accelerates as well, for regular situations). I thought we were talking about the second system being harsh.

I get why the first one would be tho, it's designed to function only when the driver already falls to, but it's useless or dangerous of it's not working properly.

Auto-brake and auto-cruise likely rely on the same radar system. Mine seems to, as they both over-react to the same things. Really they're just different applications of the same data.

Oh, yeah, they both really on radar in my case too, but you can also get my model w/o radar (and it still has that emergency braking feature).

I'm just baffled how come I never heard of it having so much issues, even irl I never heard about it being like that. The closest my system got to a "false" positive was on a narrow road (one car max) where a car coming towards me stopped on a slightly wider spot and went a bit offroad to allow me to pass by. As I accelerated directly towards the other car (to later turn to go a bit off-road only when already very close to it) my car beeped but didn't brake.

Overall the system activates for me probably less than one time per year, and I have it set on the most sensitive option (all of such safety features). Previously it was in a situation where a car coming from a side road stopped (rapidly) only when already half on my side of the road, so that was valid, tho I saw it way before that & nothing happened.
