Afaik, all of the radar assisted cruise control / emergency braking systems ignore stationary objects when travelling above a certain speed. This is false. Radar assisted cruise control definitely do not ignore stationary objects above a certain speed; indeed, detecting stationary objects is a fundamental part of how emergency braking systems work... Other automakers are simply better at determining what objects are in the path of travel than Tesla, because they actually test their systems before they release them to the public.

This article [1] is several years old, but I believe it is still an accurate summary: > Sam Abuelsamid, an industry analyst at Navigant and former automotive engineer, tells Ars that it's "pretty much universal" that "vehicles are programmed to ignore stationary objects at higher speeds." Chevrolet says [2] > At speeds between 5 and 50 mph, Automatic Emergency Braking (AEB) can help you avoid or reduce the severity of a collision† with a detected vehicle you’re following using camera technology. It can automatically provide hard emergency braking or enhance the driver’s hard braking. They don't specifically say it won't detect stationary objects on this page, but a vehicle you're following will have been in motion, or you're not following it. Consumer reports describes several types of AEB [3], none of which mention stationary objects. If you've got a reference that suggests that driver assistance features stop for stationary objects outside of parking speeds, please provide a link.

Whether it's true or not, Elon has previously explicitly stated that they ignore stationary items He went so far as saying that a can on the road was indistinguishable from a highway underpass and then went on about how they would white list every underpass to avoid it triggering But this is Elon, so I have no faith in its accuracy, but don't be surprised when people believe that the CEO is describing how their car works
