1999: “May 9, 2017. At approximately 5:50 pm, I got in my car which was parked in a small outdoor parking lot. I started it and put it in reverse and the car took off. Even though I applied the brakes the car did not stop or slow down. It slammed into a parked 2016 mercedes with such force that the mercedes was left almost perpendicular with its space. Police were called and came to scene but because the parking lot is on private property, no report was filed. The owner of the other vehicle and I exchanged information.”

2000: “On july 2 ,2009, my wife struck another car broadside with our 2000 Lexus GS400. The point of impact on the Lexus was with the left front portion (headlight area) of the front. She was traveling approximately 35 MPH, and did not have time to brake. The impact, and seatbelt, cause a moderate sized bruise on her left breast area. Lexus indicates their airbags deploy on frontal or near frontal collisions at 8 to 14 MPH. Yet, in this case, what I think is a near frontal collision, the airbag did not deploy. …”
