At least, they don't make Acura bumpers so they stand up to even mild impact. I was backing out of my parking slot at work. I think the other guy got about a foot out of his, so basically, it's pretty much my fault, since he was in my blind spot. I caved in his driver-side rear bumper pretty well (we hit corner-to-corner). I got a minor scratch in mine, which is plastic. I have no idea what his is made out of, but it obviously doesn't stand up to 2 mph very well. It looks pretty ugly. Our various insurance agents are going to talk. I suppose I can now expect to see my insurance rates skyrocket. Oh well, it happens.
