Whats the percentage of the cost of the driver for airplanes, boats and long-haul trucking, compared to the cost of each trip? Maybe for the trucking it is significant, but I'm not sure airplane ticket prices would go down significantly if we automated them. But with cars, the price of the driver is actually pretty big, at least 50% of the cost of each ride, when taking a cab or Uber. So that can be a lot of money people are saving. Plus the whole part where we might get rid of parking spaces in urban centers. This might actually change the way we build cities in the future.
