I seldom choose to respond to every point someone else makes in a discussion. Doing so tends to create expanding posts where each reply is longer than the one that precedes it. Generally, I pick a point to which I think I have the most interesting thing to say and just reply to that one. And I think lots of people do that sort of thing. So, in general, assuming that when someone doesn't reply to a point, that the reason is because they don't have an answer is ill-advised.
Stopping on regenerative braking alone isn't just about time and distance, it's about control. With a Bolt at low speeds, I can modulate the regenerative braking force across a wide range of strengths. I can stop slower or faster as desired. With the Model 3, I don't have that option. It is going to be slow. If I don't start stopping in time, or misjudge where a car in front of me is going to stop, my only means of correction is the friction brakes. That's just the way the Model 3 works. With the Model 3, a regenerative stop isn't just a slow stop, it is an uncontrolled stop: it's gonna do what it's gonna do. If you've taught yourself to (mostly) stop that way, that's fine. I got no beef with you.
