Teslas or people in general people should absolutely not break-check, but no, cars that drive so close to the car in front that they cannot safely stop in an emergency are tailgating.

I do agree there is some nuance, but it really saddens me that so many comments in this thread are supportive of a form of driving that, while very common, is unsafe for themselves and others. It's a form of normalisation of deviance and I'm sure it costs far more lives than teslas dodgy "autopilot" (even if that too should not be road legal).

In metropolitan areas (where I imagine most Teslas are driven), it often just isn’t possible to maintain a textbook-safe following distance. The instant you allow more than the average distance ahead of you, another car will jump in to fill the gap.

And?

People sometimes fill the gap in front of me, and if they're particularly unsafe about my induced following distance I flash my lights, flip them off, and back off. In a typical 30 mile drive in one of those metros it costs on the order of tens of seconds. People usually aren't that aggressive about filling gaps until they have something to gain, so the frequency of people causing you to slow down winds up being pretty low.
