This is more of something to think about, not sure it belongs here but anyway... I drive the same two lane stretch of road to work every morning. I frequently let the car do the driving for me, mostly to see how well it's handling the curvy parts. I'm curious to see if it's learning or getting better at it. But, what got me thinking this morning was just how well it was keeping me in the exact middle of the lane. So much so that I'm hitting the exact same pothole in exactly the same way day after day. Doh! But does this mean, eventually, with a road full of Model 3s on autopilot, are we going to get wagon wheel ruts in our roads?
