Ouch, that hurts to see. But it sounds like you have a bunch of good avice in the above posts. Good luck.
If the future, you might want to try what I do. As I back the car out of the garage to put the bikes up top, I place two bright orange cones in the garage just inside the door. When I come home, I'd have to run them over to get in and it's an instant reminder. Just don't ask me why I started doing this. It's a sad story.
