True story: A couple of years ago I went to a family event. There were maybe two actual parking spots (it was at my brother's house). My cousin parked her Hummer on the asphalt; I parked my Prius on the dirt on the side. I think that pretty much says it all.
My uncle's Hummer has never seen dirt roads or anything but pavement. He also doesn't drive it in bad weather because it handles so horribly lol.
