We have monster curbs here in Colorado, have to go pretty diagonal coming in and out of my driveway, not including a severe incline of a driveway after the sidewalk. But it only scrapes the plastic sport package aero thing.
I was thinking about a nice lip for later, but I just don't see it possible with my curbs and angled driveway. Sounds like you have something similar.
You can see the curb in the background of the first pic:
And how high I am from taking a picture from the top of the short driveway:
