A Tesla running the latest version of “Full Self-Driving” failed to stop at an active railroad crossing this week and nearly drove straight into a passing train, according to the driver and as evidenced in dashcam footage.

 

The kicker: it was running FSD v14.3.7, the newest build Tesla has released — and it’s at least the third time this year that Electrek has documented FSD trying to drive a Tesla into a train.

Would have been ran over by the rain had I not braked??????
The rail road crossing lights were flashing and the train horns were pretty loud. #FSD pic.twitter.com/1xZ454EbMj
