My daughter was coasting and the person in front of her slammed on their brakes causing her to slam on hers. Her collision warning did not go off until after she hit the car in front of her so she had didn't have enough time to stop. We pulled off into a parking lot and called the police to inspect the cars. Two weeks later there was a recall on the back brake pads. She ended up getting a ticket for impeding traffic which ended up costing $150.00 plus $5.50 for fees. I also have damage to the grille and bumper on my car that needs to get fixed.
