But blogger Ryan Avent has a suggestion:
What about the potential for something weighing just a few hundred pounds, battery-powered with a range under 40 miles, perhaps a one-seater with room for groceries, and with a typical cruising speed of between 20 and 30 mph?
Something like that could eventually retail for the price of a computer, would be far cheaper to run than a car, would be much more energy efficient, and would handle the basic job of getting a lot of people where they need to be. Imagine a future in which you hop in this vehicle which takes you the four miles to the nearest Metro station, drops you off, then travels to the grocery store to pick up the order you placed on your computer before you left, and finally returns to your home and plugs itself in.
