So one day you're driving down the street, and you run out of gas. And that's where a fellow in a shiny hat comes up to you, and asks why you're bothering to drive cars, and spend money on gas and repairs, when for just 25 dollars a month, you can give up your old clunker and be enrolled in a People's Collective Motor Pool, which will always be available when you want it, and extend the benefits of transportation to those who don't own cars.
