Made that mistake. Relied too much on the backup cam... until I hit a post painted bright yellow. Yellow scuffs on the black painted bumper.
Never really used the dumb thing after that. IMO, the camera is a marginally useful tool. Use it for an initial quick check, but you must turn and use the rear window while backing. You really can’t watch the backup camera while backing. Well, you could, but it’s rather confusing turning to adjust while looking forward into the backup camera.
IMO, sort of a tech gimmick. Safer just to turn and look while backing.
It can be handy when backing without clearing snow off of the back window and mirrors....
