Just to clear things up, the Tesla turned off of the road and onto train tracks.
Tesla’s “Full Self Driving” mode requires the driver to pay attention the entire time. For common things like not stopping on train tracks, the driver is expected to perform this. Obviously, that’s not “Full Self Driving”, but it’s something that you can get used to.
On the other hand, turning onto train tracks is unforgivable. In an unfamiliar area, the driver may be confused about what is the correct place to turn, especially in the early morning as this was, and it might be natural to defer to the car’s superior knowledge of the map and GPS. As a driver, it would be hard to imagine that the car would turn you on to train tracks.
It’s supposed to be trained to drive like a human, but I expected it would drive like a human who had immediate access to extremely detailed map and GPS information.
