ok, at low speeds acceleration of the car from a stop is the biggest issue. then comes rolling, and then aero.
I mis"spoke".
But still, rolling resistance is not nearly as important as the energy to start and stop the vehicle in typical city traffic.
Interesting that you put most of your miles at under 38 mph. Do you feel safe at those speeds on the freeway?
