The BMW i3 has an interesting feature which could be added to the Model S with a simple software update.
In slower (city) traffic, the accelerator pedal works in regenerative mode. When you let go of the pedal, the car "brakes", which means that you hardly ever have to touch the brake pedal. This single-pedal control is a very efficient way of driving with a single foot in start-stop type of traffic. (Although I know that some people don't like it. You can disable this feature in a MS).
However, at higher speeds (highway), the accelerator pedal works in coasting mode. When you let go of the pedal, the car simply coasts, as if you would have put it it in neutral. This allows for a more natural flow and more relaxed driving on highways. You can lift your foot of the pedal and relax you muscles, while loosing a minimal amount of energy built up by inertia (braking would be counter-productive in those circumstances).
The speed-sensitive accelerator pedal certainly would be something to get used to (now it brakes, now it doesn't). But what's your take on this feature? Should Tesla add it? Why or why not?
