Why is it that every time I hear a story about efforts to improve vehicles, I say to myself, "Gee, hasn't that been done already?" All these efforts seem to have one thing in mind: get a car to act like a train, that way we can continue subsidising the auto/oil/rubber industries with the needless purchase of more individual rail cars.
How about a challenge to develop real public transit in the U.S.?
Sorry, I live in L.A. and I'm bitter.
