Will Robot Cabs Unjam the Streets?
An anonymous reader writes: The Atlantic has a story with some video of a traffic simulator showing just how the roads can be jammed up by people looking for a place to park. (You can play with the simulator too.) This has been suspected for a long time by many traffic researchers and city planners, but the simulator shows just how quickly the roads jam up after just a few of the blocks fill up with parked cars. The good news is that autonomous cars don't need to park-- they just go give someone else a ride. They could change city life forever.
There is a way to make it happen, but I doubt it will fly. Korea basically did this in the 1970s and 1980s. The government knew it didn't have the road infrastructure to support every household owning a car, so they taxed cars up the wazoo. A car that might cost $10,000 would cost $50,000 after taxes ($100,000 in today's dollars). This had the effect of severely discouraging car ownership. In its place, a robust taxi industry sprang up. I remember visiting downtown Seoul and 80%-90% of the cars on the road were taxis. There were no traffic jams, and if you didn't want to wait for a bus you could hail a taxi within 15-30 seconds.
It all fell apart in 1988. One of the Democratic nominees for President (Gephardt if I remember), in a bid to win Michigan made a huge ruckus about how Hyundai was allowed to sell its cars for $6000 in the U.S., while an equivalent Ford cost $45,000 in Korea. He conveniently left out that the same Hyundai also cost $45,000 in Korea. He didn't win the nomination, but the damage was done. U.S. public sentiment forced the U.S. to pressure Korea to remove their car taxes. Cars in Korea suddenly became affordable to the average household, and Korea plummeted into two decades of gridlock.
