There is probably more to this story than is being told right now. The Tesla driver had a green light at 03:45 AM but ended up crashing, killing a teenager, before getting arrested.

First responders also treated the driver of the Tesla, 27-year-old Nicholas Williams of Herndon, Va., on the scene. Officers then arrested and charged him for Driving Under the Influence and No Permit.

Drunk in an intersection crash just before 4AM with no permit? Probably was asleep and drove full speed into the other car

Sounds like another case of failed “Autopilot”.
