There are some driveways that I cannot make into at all. Most I can approach at an angle, but I picked up a girl for a date and I just happened to ask if she had a steep driveway. She said, "Actually I do..." and I was going to bring my SUV, but I ended up bringing the Nismo 'cause, well, yeah.
Anyway, I took that thing at the most conservative angle possible and cleared the nose, but had I traveled another inch or two forward, I would have been high centered. I parked it and walked to her door, haha.
I've actually managed to never scrape on anything up to this point... but that one was seriously close to being catastrophic.
