Most (all?) other cars have radars for this. They do not seem to experience as many problems as Teslas, which is especially telling considering how much more other cars are on the road.
I mean, plenty of people drive dangerously anyway. I'd rather most people brake abruptly than drive 20mph above or below the flow of traffic, weave dangerously, pass on the shoulder, run red lights, fall asleep, drive drunk, etc. If they get in a car that's merely "too cautious", that's a pretty big net win for society.
I have a 2019 and I've used autopilot extensively and i've never had it break when it shouldn't. I've had it beep at me erroneously maybe twice, so I think this is something in the settings that is causing the issue.
I have a 2022 and it phantom brakes all the time. We haven’t touched any settings and if it were a settings issue, I’m sure someone in the Tesla community would have figured it out (there are a lot of Tesla’s out there and yours seems to be the only one that isn’t affected). Moreover, a phantom braking setting would be pretty insane—I have a hard time believing they prioritized a phantom braking feature over, say, more media app integrations.
