> You're ignoring breaking. If you go significantly faster than the speed limit your far more likely to break at highway speeds. I'm not ignoring braking. Aggressive driving wastes a lot of fuel, but aggressive driving happens regardless of the posted speed limit. In fact, that rapid acceleration-brake cycle is more likely to happen when the flow of traffic is below the speed limit. > Further, IC cars often get better fuel efficiency by mixing slow acceleration periods at optimum RPM and coasting. (Car engines get ~10-30 efficiency based on usage.) You can do this manually, but it's hard. I don't think it's hard. It just requires paying attention to the traffic around you.
