Reality is that about 99% of the time I don't run over or hit anything either. (which is good
)I however live in a new neighborhood that has some rather tall curbing. I live here so I am now familiar with the fact that you drive at an angle backing out of my driveway or you will scrape your front bumper and/or the under side of your car.(ASK Coribug)
) When I back out of anything, (I don't know about you) I go slow, so this is NOT a matter of carelessness. I know that I do not live in the only neighborhood that has these kinds of curbs, not to mention other establishments. I have ALSO slightly scraped my under side on certain speed bumps. AGAIN, I do not go fast, nor do I go OFFROADING. Point is, in certain situations some scraping occurs. The OP asked about skid plates and I believe we answered him. This is not a debate over who is a Kamikazee driver and who isn't.
