My wife has trouble backing up in our driveway. Because the view out the rear window is limited (can't see landmarks near the ground), we've worked together on using the backup video exclusively. For example, she has the two guide lines go exactly between two reflectors that I've set up, and when the tip hits a third reflector, she starts the turn. Also, I like to back the car into the garage even though it's a little tight. I was thinking that I could paint or tape some lines onto the cement that could be lined up with the lines in the backup video display. That could make things very easy. Anyone do anything like that?
