You see, the issue we got with this kind of system are the idiotic drivers that cuts the truckers. The system panics and automatically brake which sends the trucker almost to the windshield and from reports from many drivers, it's like the system grew an extra set of brakes out of nowhere and brake even better than yourself with your foot on the brake pedal at the maximum of your strength and the Maxi brakes on at the same time til' the danger is gone. But then what happens behind? What if the cars can't brake as hard as you? A whole new kind of accidents will happen.
