I'll be happy to volunteer on that.
I first confronted this when the hurricanes took out capacity and we really had a spike in gasoline prices. We put together some information for Canadians about how to save on gas, and I felt maybe I should actually put some of them into effect myself, as opposed to simply telling people what to do. So I slowed down from 100 kilometres an hour to 90 kilometres an hour, and I found that I actually got to my destination in exactly the same time. My brakes were used a little less frequently as well.
I don't mean to be facetious about this. There are options that Canadians can pursue to reduce gas consumption in the short term. Don't make unnecessary trips. If you have to go to three places in a day, do it at once, and don't make three separate trips. If you can get people together to go on the same trip, by all means do that. Make sure your tire pressure is properly inflated. Most important of all is to slow down.
