Imagine a city where you don’t drive in loops looking for a parking spot because your car drops you off and scoots off to some location to wait, sort of like taxi holding pens at airports. Or maybe it is picked up by a robotic minder and carted off with other vehicles, like a row of shopping carts.
Inner-city parking lots could become parks. Traffic lights could be less common because hidden sensors in cars and streets coordinate traffic. And, yes, parking tickets could become a rarity since cars would be smart enough to know where they are not supposed to be.
As scientists and car companies forge ahead — many expect self-driving cars to become commonplace in the next decade — researchers, city planners and engineers are contemplating how city spaces could change if our cars start doing the driving for us. There are risks, of course: People might be more open to a longer daily commute, leading to even more urban sprawl.
That city of the future could have narrower streets because parking spots would no longer be necessary. And the air would be cleaner because people would drive less. According to the National Highway Traffic Safety Administration, 30 percent of driving in business districts is spent in a hunt for a parking spot, and the agency estimates that almost one billion miles of driving is wasted that way every year.
