Vision rather than radar AEB isn't that uncommon though is it? My cheap Suzuki uses stereo cameras for AEB, and it was touted as a pro by the used car salesman as it can detect stationary objects (which radar-based AEB can't). Sounds like Tesla needs to tune theirs better but that can be done in a software update, I'm not sure I buy the "they were fools for removing the radar hardware!" since when the radar hardware didn't prevent Teslas from running into stationary hardware they were lambasted for that as well.

Subaru also uses a similar stereo camera sensor for their AEB.

  How well does that system work? I test drove a vehicle a couple years ago and found it to be mediocre at lane-centering, much worse than the few Teslas I've ridden in.

    I've never actually needed the automatic emergency braking so can't say how well it works. The dynamic cruise control works pretty well and will brake when necessary to maintain a safe following distance. But if you're driving on a freeway in the slow lane and the car ahead takes an exit then EyeSight sometimes gets confused and thinks the other car is still in your lane. So it brakes when it shouldn't until the other car moves further off.

If you can get your car to beep at you when an object is close in front of you (either by being in reverse or by pressing a button to turn it on) your car is equipped with radar.

  Yeah it doesn’t do that from stationary. I’ll only beep if I’m going full speed at a fence or something (like at a 90 degree corner). No parking sensors either. It has a 360 degree overhead parking camera view for parking though.

  Parking sensors use sonar.

Radar not being able to detect stationary objects is a weird half myth. Car manufacturers disable AEB at high speeds and program it to ignore stationary objects but not because the radar can't detect objects that aren't moving. https://arstechnica.com/cars/2018/06/why-emergency-braking-systems-sometimes-hit-parked-cars-and-lane-dividers/ https://arstechnica.com/cars/2018/06/why-emergency-braking-s...
