After driving the Model S for a couple of weeks now, I'm realizing that I have to modify some of my defensive driving habits that I've learned over the years. The most obvious is "covering the break" (taking your foot off the accelerator pedal and hovering over the brake pedal) which I do so often and instinctively, I don't really even think about it anymore. With the Model S, there is less of a need, because the accelerator pedal has enough "braking" capability that it works in most (but not all) circumstances. However, I have had circumstances in the past where I want to be prepared to brake hard, but still keep "coasting" in the meantime. This seems more difficult in the Model S, and would require me to hover over the brake pedal with my left foot. The other behavior is using the brake pedal to signal intent to the driver behind me. Maybe they are following too close so I'll give a light tap on the brake, to give them a heads up before I really start braking. Or sometimes a few taps to "flash" the brake lights. This is a little harder to manage, since it is not obvious when your brake lights are on during regenerative braking. Anybody else having to adapt their defensive driving behaviors?
