Not entirely true. Some states in the United States have "brake checking" traffic laws, and others that do not have such laws can issue a citation for reckless driving in a case of brake checking. Like a lot of "road rage" stuff it probably goes underreported and under-prosecuted. (brake checking is going to be a lot easier to prove in the near future when cars are littered with cameras)

Neither would seem to apply to an automated system that randomly stomps on the brakes. I would think a system like that might affect fault on the civil, rather than criminal, side, however. For example, it would seem a bit mad for the insurance companies not to blame the vehicle whose screwy brakes caused a multi-car accident.
