I'm sure it's more complicated than it seems (or maybe not), but that video is pretty damning. It's not like something is blocking the car's view, the lights and crossing bars are very visible. Car just doesn't notice / keeps going.

I'm trying to understand if there is a situation where driving into a red and white stripe with flashing lights on it is correct. Does the Tesla think that because there isn't anything below the crossing arm, that the arm is actually farther away? Or it looks vaguely similar to the back of a trailer, but not enough so that is ignored?
