You got the point, though. We have a society that has based a lot of its entertainment on either twin-cycle or internal combustion engines. We do use energy profligately.
I truly believe that if we cut back by half our use of gasoline, we'd be in a better position to make full decisions and plans to reorganize "the social order" to stave off disaster.
I still think that if metro areas insisted via laws to curtail single-driver commutes (though the use of multiple diamond lanes) and design city traffic so that some streets could be dedicated to low-power devices and bicycles, more buses, etc., that we could grab hold of petro use. Additionally, issue gas ration cards for all registered drivers (with a maximum of two per household) -- these could be used or sold to others.
Vehicle-Miles Traveled This is a comprehensive set of graphs and statistics about the amount of miles driven by the "average" household, comparing 1988, 1991, and 1994.
An average vehicle, therefore, traveled farther in 1994 than in 1988: 11,400 miles per year compared with 10,200 miles per year (Figure 3.2). Because the number of vehicles per household remained steady at about 1.8 from 1988 through 1994, per-vehicle and per-household mileage grew at about same rate. The per-household average rose from 18,600 miles in 1988 to 21,100 miles in 1994.

Light trucks' share of total vehicle-miles traveled rose from one-fourth in 1988 to one-third in 1994. The increase was the result of two factors. Light trucks comprised a larger share of the residential fleet in 1994. In addition, two segments of the light truck fleet--minivans and sport utility-vehicles--were driven more miles per year per vehicle than were passenger cars.

Teenagers in the Household Boosted Miles Traveled
In general, people in households with children drive more, and those with driving-age children traveled the most vehicle-miles of any category in 1994: 29,900 miles (Figure 3.7). First, the presence of children of driving age tends to increase the number of drivers in the household and, therefore, to increase the number of vehicle-miles traveled. Secondly, older children may create additional travel demands than do younger children. In households with younger children, the number of vehicle-miles driven is similar to the number of miles driven in households with two or more adults with no children and in which the householder is younger than 60. In fact, households with two adults or more registered the greatest 1988-to-1994 increase in the number of vehicle-miles traveled.

Higher Income Correlates with More Driving
In general, higher income is correlated with more vehicle-miles traveled per household (Figure 3.9). Annual household income of $50,000 or higher, when coupled with the presence of teenagers of driving age in the household, boosted average vehicle-miles traveled per household to 40,200 miles in 1994. And in households with that income and with two or more adults and no children, vehicle-miles traveled averaged nearly 27,400. By comparison, in those households with annual income below $10,000, vehicle-miles traveled averaged only 13,200.
