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.
Fuck off. Don't act like this is about substance abuse issues. Countless addicts and alcohols do not drive drunk. Get drunk all you want, do whatever drugs you want, but the moment you step into the drivers seat you're a piece of shit who deserves whatever is coming. Don't act like a victim for pointlessly endangering random people's lives.
