LDB, to get the best AER, it is better to coast to a stop if you aren't going to hold up the people behind you in traffic. Regen is 50-60% efficient (75% in some situations?) but coasting is near 100% effective in not using any juice in the first place. Getting the best range only works, though, if you aren't going to make everyone around you hate electric cars even more because many ICE drivers don't mind rabbiting it around by gunning it out of the stop light light and slamming on the brakes at the next red light. They got tons of range and most don't realize that they are killing their mpg, or don't care.
