I was rear ended recently. Broke some bones, am now on a cane from crutches. The person who rear ended me fought hard to say that I caused the accident by stopping short. Luckily, my state law says if you rear end someone in traffic, you clearly were:
A) Not paying attention
B) Traveling too fast for the conditions
C) Traveling too closely for traffic conditions
Had I had a reverse facing camera, it would have shown this asshole following very close to my cars rear end for well over 3 miles. I did not break check him. My guess is he looked down at his phone or radio instead of watching my taillights that were 14 inches from his front bumper and never hit the brakes, instead deciding to use my truck as his choice of "brakes".
Regardless, he got a reckless driving ticket and insurance rates that went higher. I got a trip to the hospital, my medical bills covered, and reimbursed for a totaled vehicle. Oh, and a reverse facing camera.
