When backing up in a new poorly lighted parking deck, the safety warning beeps did not happen. They beep when I am close to anything any where but when I really needed them before hitting a huge support column for a parking deck resulting in damage to bumper, liftgate, and rear window, and me!

I paid a lot of extra money to ensure my safety due to physical limitations turning my head. All of those expensive safety features failed - back up camera, beeping, braking!
