Hi Maybe there are some engineers out here who may have figured this out already. Do you think it's more efficient coming to a complete stop; gaining 100% regeneration of energy, or not quite stopping completely? Not that I condone not stopping completely at a stop sign. Do you use less energy with a rolling "go" than you would gain by completely stopping the car? I know traditionally you use less gas by a rolling "go" than coming to a complete stop, as it takes more energy to move the car forward from zero. Steve
