You don't spend a lot of fuel accelerating, that only takes a few seconds, it isn't a prolonged action.

Heck. That must be US highway speeds, I guess. Over here, our highway limit is 120km/h in non-built up areas, and 60km/h in suburban areas. Consumption for most vehicles are best at around 80 to 85 km/h in high gear, which means your motor is ticking over very slowly. At legal limit, 120km/h, your car will almost use double per 100km what it would have at 80km/h, for 100km. This is due to higher revs burning more petrol and more stress on the engine due to increased wind resistance. So - quick solution would be for governments worldwide to lower highway limits.
Won't help you much with town driving, stop/start is a killer in anybody's books. But there's a lot of things you can still do, like taking your car out of gear when going downhill.
