If it brakes when you back off on the pedal it very probably is regenerating though the regenerated power may be dissipated in a resistor rather than used to charge the battery (i.e. thrown away). Regen is found on many electric vehicles. If you have a controller sophisticated enough to let you control an AC motor as easily as a DC one (and, of course, we do) there is no reason not to attain the benefits of single pedal control, improved mechanical brake longevity and energy efficiency. Some may not care so much about the third (energy recovery) but that is probably the most important to the designers of these cars. My X 100D wouldn't get 300 miles on a charge if it didn't have regen. Range anxiety is still the major factor that frightens people away from BEVs. It is absolutely essential that the manufacturer squeeze every mile of range he possibly can out of his design in order for him to be able to sell his car. In my X, for example, the door handles are flush, the car is shaped like a bullet, the cell and GPS antennas are flat and it has regen. It's pretty clear to most what benefits regen grants but I agree that there should be a way for the unsophisticated driver to turn it off if he wants to. I suppose these folks should be able to set the sound system to mono and the displays to black and white too but I don't think any manufacturer offers that.
