Because Tesla’s safety features apparently make it so that you can get away with driving drunk. Dude was obviously drinking a beer and everything. They told him they could tell he was drinking, to warn him because while they weren’t going to narc on him, someone definitely will, and he just sort of absentmindedly smiled.
I guess you can narc to under and not involve gunmen. Still getting him fired is harsh but thats the public safety goal.
