Teslas and other manufacturers will trigger at speed against a stationary vehicle detected by the adaptive cruise control system.

Teslas are beginning to trigger more at speed on perceived non-vehicle obstacles (added in a recent OTA update) but that is not without false positives which some have deemed the Tesla Brake Check.

I’ve experienced the errant braking, typically when a lane is partially obstructed but you are moving to avoid the obstruction, that is when it will trigger. I’m not a fan of this behavior. You can override it with a quick tap on the accelerator, but it jostles you.
