My former house was on a deceptive corner that not only was banked the wrong way, it also had a frost heave about halfway thru that wasn't obvious unless you knew it was there. I lost at least one mailbox post a year for the first 10-12 years I lived there. Was a 2' dia pine tree just past the mailbox that had many a chunk missing from it too. It seemed to be mostly teenagers/early 20s drivers.
One time a young lady in a brand new Mustang took that corner too fast and ended up backwards in a wooded section in front of the house, going over a somewhat fallen-down stone wall in the process.
What undercarriage components didn't get trashed going in got it when it was winched out by the tow truck. Car couldn't have had more than a couple hundred miles on it. Expensive lesson.
After a while either all those kids moved away or else wised up about that corner as accidents dropped dramatically. Still, it wasn't a driveway you wanted to back out of.
