After reading about some unfortunate mishaps bumping into garage walls and doors, driving away with the trunk open, etc., I thought I'd try to pre-empt my inevitable lapse in attention someday. I bought a swimming pool noodle and cut it up to make a bumper on the open garage door, and put a tape line on the floor of the garage so I can watch for it in the camera to know where to stop so I don't hit the shelving in front of the car as I pull in. No mishaps yet, knock on wood...
