It struck me other day that there is a very easy way to signficantly reduce the US fuel demand; that is to say, easy compared to many other options. In anticipation of the Los Angeles Summer Olympics, in what year...1980 I think, LA made a great effort to reduce traffic on the roads by, among other thing, asking companies to stagger their work shifts. Completely voluntary, by spreading the traffic out, the effort was so effective that in fact when the Olympics came, the freeways were as empty as I'd ever seen them. There were no traffic jams. IIRC, a car uses about 30-50% as much fuel when idling as it does driving at full speed. This may have improved in recent years, but I would bet that the fuel consumption at idle is still significant. I also know that LA [city] living can mean hours stuck in traffic with the engine idling. So, using this logic, it seems possible that we could reduce demand in the cities by managing the traffic patterns more effectively; esp by staggering shifts as was done in LA. In principle and shooting from the hip, it would seem that we could reduce demand by as much as 50% [for some sectors of the population] or more. Consider that during peak hours, the average freeway speed is about 20-30 MPH or less.
