I have HD surround vision cameras. I was parallel parking very slowly. The back end of my truck was in so I was watching the camera to see the front right of my truck and the back left of the other vehicle. I could see both vehicles including the road between them. There was space between the vehicles on the camera when I hit the other car. I called Sewell Buick Gmc and explained the camera might need calibrating. They sent a loaner car and picked mine up, When the driver arrived I explained the situation. It surprised his so I said get in my truck and put in reverse to activated the camera and watch me as I walk toward the right front tire. He saw mw as I approached, however, when I got right next to the tire I disappeared from she screen. GM said the vehicle was operating as designed. Operating as designed? They designed a SURROUND camera to show objects until they get next to the vehicle. Imagine if it was a toddler.
