This morning I took my wife's car in for a repair and was on a US highway (very wide margins on both sides), where I spotted an unlucky and probably foolish driver had his car up a bank, pointed the wrong way. My guess is they were driving too fast and hit a puddle, losing control badly enough to end up going in the wrong direction. To do this the car had to go down a shallow bank, probably 40' wide, across a shallow ditch, and up a steep bank. If nothing else the front and back bumpers hit dirt, so damage is likely. I'm sure the driver needs clean underwear.
A few miles later was my turnoff. I've driven this route literally thousands of times, but given the total downpour and the linework badly faded, I had a hard time figuring out where the turn lane was -- I judged it by where I thought the edge of the pavement was.
I have difficulty believing that software and sensors can make judgment calls better than a driver in such conditions.
