We Once Had Self-Driving Cars
A frequent response to the dysfunctions of American air travel is technological: namely, self-driving cars (also see this article). In a self-driving car, you can relax, even sleep, while being driven safely to your destination at 60 mph. We once had such a system. It’s called a train network.
Compared to air or car travel, a decent train network is cheaper, more environmentally friendly, and quicker. As an example, I’ll compare two door-to-door, city-center-to-city-center journeys.
