Has anyone determined if there is a technique for braking to maximize the amount of kinetic energy put toward regenerative braking versus going to the regular old brakes? That is, given that you know you have a stoplight coming up some distance ahead, is it best to coast a long time and then brake harder near the end, or to "ride the brakes" for a longer time? I can watch the green bars that indicate "charging" but I wonder if it is best to max out the green bars for some of the time, or to avoid maxing them out to get longer time duration at not-quite- maximum on the charging display.

It seems that you'd want the regular old brakes to do the least amount of work (within the realm of safety, of course!), so that the battery gets maximum recharge.
