“I was driving my vehicle straight ahead on a two-way city street with no other vehicles in front or on my sides. I was traveling at a speed of 40 MPH. The two-way street is separated by a concrete divider and trolly tracks. A brake! Alert appeared on the display screen followed by beeps. Suddenly the brakes were engaged bringing the vehicle to a complete stop causing the vehicle behind to come to a screeching halt. In a few seconds I was able to drive off.”
