Pat this last year, I was at a standstill due to an accident ahead of me, on hiway 101. A women on a cell was doing 35-50mph by my estimate, when she looked up and plowed into the car stopped behind me. The impact threw the car behind me into my rear end pushing me fowards. I guess she didn't stop right away because she nailed the car behind me again and in turn I got hit a second time.
About 5 months later, my wife was rear ended on the same hiwy in heavy traffic because somebody behind her wasn't paying attention. A driver's license is a serious thing!
