I had the same accident recently, because construction crew at my apartment complex left a big chunk of concrete in the driveway, cutting my available backing distance to 2/3 of its usual. The chunk of concrete was not visible from the driver's seat, even though I always turn my head around to back up. Repair at dealer = ~$620. The extra $120 is not worth insurance fraud, guys.
And of course the rear visibility of the current Accord sucks, especially compared to the last two generations. Especially in the Coupe.
Also I agree with the above assessments re: the weakness of the bumpers. I was hit from behind in my 92 Accord EX-R at about 30 miles an hour by a Lincoln Continental. My bumper was scratched but my muffler took out his front grill and his radiator fan!
