Devilstower on Daily Kos wrote an excellent piece yesterday about how quickly cars in the US have changed. Following the Oil Crisis in the seventies lower speed limits encouraged smaller, more efficient cars. Over the last twenty years what had been a massive increase in MPG by the eighties has slowed and stalled with the advent of the SUV and bigger vehicles all round. Now a few manufacturers are producing incredibly efficient small city cars and hypercar such as the VentureOne and the Aptera. Having had a break from the trend towards smaller cars, is public thinking returning to the idea again?
