The first one hit me square on the rear end. I was at a dead stop behind the van, and she hit me at 30+ mph, never even touched the brakes. Everything that could hold liquid on the car, except the windshield washer, was busted. I had to get out and shut her car off before she blew us all up - the front of her car, engine running, was sitting in gas from my ruptured fuel tank, and I had just filled it up. The second one was also square on, but we were both moving, so the impact wasn't as hard. It was enough to make me lose control and hit another car in the next lane over, then the first car hit me again and knocked me off the ramp. We went end over end and landed upright, and my passenger and I both walked away. I wore seatbelts in both wrecks - have since I got bumped off the track and rolled a stock car over three times 'way back when. My passenger in the second wreck had never worn seatbelts in his life, until that night - he saw me put mine on, and put his on as well. Saved him serious injury, and possibly saved his life.
