Whoa! For your refutation, Willie.
What's to refute?
Under different sets of conditions, it's always possible to fabricate a scenario where one mode of transportation is more fuel efficient than another, no matter which side of the debate you're on. Heck, bicycles are more fuel efficient than either cars or trains.
The car's superiority rises dramatically when compared with trains travelling at up to 215mph.
This particular quote is just one illustration of the apples-to-oranges analysis presented in this biased article.
Does the car's "superiority" hold true if the car is ALSO traveling 215 mph???
Hmmmmmmm?
Doh! I don't think so!
