Self-driving cars dealing with those barefaced acts of repeated brake-checking by human drivers
We’ve all been brake-checked at one time or another.
Brake checking refers to the notion that a car ahead of you will pump on its brakes to try and send you a signal. Presumably, the signal primarily being conveyed is that you ought to slow down. In addition, the same signaling usually is trying to warn you to back off and keep a greater distance between your car and the car that is doing the brake checking.
