I found some information recently about the gasoline rationing which was in place in Canada and the U.S. during World War II. Motorists were allotted four gallons a week at first and later three gallons or a little more than 11 litres a week. My fuel consumption in 2011 averaged to less than half the allotment during the most stringent period of rationing. Most of my short trips were by bike or on foot. The car was used for longer travel. Transit is not an option for me since we do not yet have a scheduled transit service where I live.
At no point did I feel hampered or restricted. For me, the limited driving simply makes a lot of sense.
