Almost every Tesla I pass at night has the headlights set to "sunburn." I dunno if it's the nature of the hardware, some kind of over-zealous automatic adjustment, or if Tesla drivers are just like that.
The Tesla cruise control feature turns the 'auto' high beams on every time you activate it and the feature is really poorly implemented. The camera it uses to detect other cars will loses sight of you when you get close and it'll flip the highbeams on in your face.
It does have that feature, but it's worse than just leaving the high beams on. It uses the cameras to try to detect cars. It detects cars way later than my old Mazda used to and then right as the car gets close to passing you, the camera loses sight of it and flips the high beams back on. Looks like you are trying to intentionally blind people.
They also have a 'feature' where they automatically brake check the car behind you if you're using cruise control on a bendy road. The computer interprets oncoming traffic as an imminent collision and slams the brakes.
