Where car sharing once resembled a rent-by-the-hour system that was a more decentralized version of the traditional car rental, it has now become a ubiquitous system that includes shared use and even cars that drive themselves.
With the backing of the House and Senate, Republicans and Democrats, automakers and auto drivers, 54.5 miles per gallon (MPG) is now the law. Many are already driving cars with better than 54 MPG thanks to innovative programs from Zipcar, Enterprise, Hertz, car2go, and other car sharing providers.
