Thats funny I stumbled across this, I've had my new hoe for 2 weeks now, 4 days after I bought it some woman rear ended me at a red light, I resisted the urge to pull her out the drivers side window by her hair and got her information only to call her insurance co. and find out her policy cancelled and she has no insurance. So I feel your pain XM Dude, I'm in PA and at least hear if you turn it in under your uninsured coverage your rates will go up and it will actually get paid as an at fault acc. on your part.
But anyway I never thought about it damaging the reverse sensors, the woman had a old ford tarrus and actually went under the trailor hitch and hit the spare tire more than anything. the sensors seem to be working fine, but where exactly are they located?
