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.
