“I was sitting in my 2003 Lexus IS 300 4 door it was a rainy and unusually cool day so I rolled the windows down and with the car idling I listened to some music and contemplated where to eat dinner it being around 5.30 pm. Suddenly the throttle opened up and the car shot off like a rocket over the curbing through some bushes and into a pond maybe 15 feet away the car was moving so fast that as it was sinking it moved out about 20 feet. It was completely submerged and I was lucky to unbuckle the seat belt and climb out the open window and swim to shore the only injury a sprained ankle. …”
