In my two years, I've backed up into two cars. First, a parked cavalier late one night whic I walked back into the bar to let them know what happened, and then the other just this month when my neighbor was backing out of a spot accross I was backing out of.. we met in the middle of the street! I've since installed a cam and already avoided a few crazed drivers speeding through parking lots, and a cart or two. No damage THANKS TO CLADDING!!! but did total 4 Thou to other cars at idle speed!
