Being cut-off on the road is triggering. Being brake checked on the road is even more triggering, but a brake check followed by a car crash is the ultimate trigger. This car had no mercy for the vehicle behind it and the brake check victim’s dash cam caught it all on video.
Next, another car had no brake check to warn of a nearby bad driver. While yielding to oncoming traffic...BOOM! This car found itself a victim of a rear end accident.
