I went up my friends driveway and part of it sticks about an inch or so above the rest. And he's got a pretty steep driveway as it is. I forgot to swerve into the grass to avoid it like I usually do and I scraped a nice bit of paint off the lip. Realize, that OEM lip is only about 6 inchs off the ground. I clear my driveway by no more than an inch when I back out.
