most of the efficiency benefits we stand to gain with forced induction and other improvements is routinely lost because people cannot drive properly. the race to the next red light does nothing but wreck your mileage. some have suggested regenerative braking as if this isn't on many cars, but it has been in use but it does not necessarily have to be with large battery packs to make a difference. When combined with auto start/stop it can keep a slightly larger battery charged enough to extend engine off time.
