For me, it has all been due to route choices and timing lights/traffic. My car doesn't P&G so well, but at < 45 mph, I can neutral coast for fairly long distances.
In my opinion, for a hybrid option anyway, a DC motor setup would be the way to go. I couldn't see needing to go faster than 10-15 mph, and for that, the amps are going to be more important than the volts. You could probably do that with a 48-volt system, but given the weight difference, Li batteries (~16 cells) would be the way to go. I'd have to do more research, but maybe 200 lbs for the whole system?
