Nevertheless, Tesla’s radar was capable of detect potential accidents “two automobiles forward” that drivers could not even see, in order that seems to be a security profit misplaced. And when radar was discontinued, the corporate had a spate of “phantom braking” accidents the place the system mistakenly calculated a automobile was about to collide with one thing — triggering an NHTSA probe.
