If only there was a way to avoid the place where trains drive.

I checked first. They didn't make a turn into a crossing. It turned onto the tracks. Jalopnik says there's no official statement that it was actually driving under FSD(elusion) but if it was strictly under human driving (or FSD turned itself off after driving off) I guarantee Tesla will invade privacy and slander the driver by next day for the sake of court of public opinion
