reduce car weight, support alternatives to cars, and reduce automobile air pollution.

• Proposed "Truth in Energy" legislation should provide that buyers of all cars (used as well as new) be given information about car weight and miles per gallon of gasoline. Since most cars are bought used, a labeling provision is especially important for them. This would have to be a local responsibility. Whether buying a new or used car, better consumer information could have an important effect on demand, and thus on eventual energy savings and reduced air pollution.

• A federal tax should be added to state license taxes (already on a weight basis) for all cars over 2,750 pounds, to go to a public transit trust fund. (See recommendation (3) below for a description of the fund.)

• The federal gasoline tax should be amended to assess a higher gasoline tax on cars that weigh more than 2,750 pounds to go to the public transit trust fund. Large cars would pull up to pumps set to include the higher tax in the metered reading. The FEA would provide car weight information annually to all registered gasoline dealers. The tax increase should be earmarked for a public transit fund. Revenues would go to states to assist public transportation systems according to a carefully developed formula. The formula should take into account commuting mileage and patterns, and population size and density. The U.S. Treasury should collect all the revenues and make sure that distribution occurs fairly.

  Consideration should be given to providing a greater proportional share to metropolitanwide, intercity, intermetropolitan, and cross-county systems. Some of the trust fund should be earmarked for innovation in flexible small vehicle group systems to serve sparsely populated areas. If successful, some of the systems could be spun off for private operation after testing.

  States and localities as well as the federal government can benefit from lower weight cars and better public transportation. This means less wear and tear on streets, roads, and highways, and reduced maintenance and repair. Air pollution could be reduced also, improving public health. Reduced air pollution would help communities and businesses that must use services to clean buildings affected by dirty air.

These transportation alternatives address demand as well as supply. They ought to slow down rapidly increasing energy use, and improve air quality and daily transportation conditions at the same time. Federal support for urban transportation, excluding money for airports, was estimated at $2.2 billion for fiscal year 1975; space research and technology received $3.3 billion. It is a
