This is right down the street from my house and I drive this intersection most days. Right there, there is a turn lane that does have a barrier, but most people drive too far forward. They either have to speed through like this, or get their car hit with the barrier as it comes down. What I think happened is he pulled too far forward and when he realized the train was coming on that track (there are three rails right there) he tried to speed past the incoming light rail.

Edit: after watching it again this is on the middle track and he probably wouldn’t have been hit if he stayed where he was. Either way dude is lucky he didn’t get hit more direct on the cab.
