At the risk of being quote happy...
If that is the metric then Cato guy could just as easily argue: "Studies show that bicycles are by far the most efficient way of moving a human being.
That's why he calculated distance traveled per cost. I think it's safe to say that transportation is about moving people and things, so considering the amount of people and things moved is pretty reasonable.
Or only slightly less absurdly: "Air transport is wasteful. We should have only highway and low speed rail transport. They are demonstrably more efficient ways to move both human beings and freight" and: "disproportionate numbers of airline seats are occupied by tourists compared to highway usage. (true) ergo, government support of aviation is wasteful."
You do realize that the first half of his thing had nothing to do with fuel efficiency, right? Anyway, feel free to post your own stats doing a similar comparison between air travel and investment. I'm not really sure how that would come out.
Also, you guys are really focused on his use of the word tourist when that wasn't nearly the focus of the analysis. The tourist charge was an implication of the argument, not a premise.
His assertion that TGV is less fuel efficient than air or automobile is, well, false.
He made no such assertion. He said that in the coming years the fuel efficiency of cars and planes will continue to increase, closing the gap.
1. HSR is being built all over the world at an accelerating pace.2. HSR kills air transport at distances up to about 350 miles.
1. Ahh, the old bandwagon argument. Shall we jump off that bridge before seeing what's below?
2. O'Toole didn't say otherwise. He only questioned whether the investment required to GET to that point was worth it, which is a fair question.
I'm sorry, but you guys seem to be letting your support for rail blind you to the arguments of those who question it. It's one thing to disagree with evidence--even disagree silently!--but I'm seeing a lot of people here who read what they wanted in this essay instead of what O'Toole actually said.
I'm unconvinced. There doesn't seem to be any solid evidence that trains will never be as fast as typical jet airplanes, and even if trains never go faster than 220 MPH, if a roomette on an overnight train that covers 95% of the miles at 220 MPH sells for the same amount of money as a coach seat on a plane, I suspect many travelers will prefer the roomette.
Physics starts to get you as you try to run faster and faster. The air just doesn't get out of the way fast enough at ground level. That's an advantage planes have that trains just can't match, and, in my mind at least, whether trains can use their other advantages to catch up is still an open question.
Also, it's not as if air travel is standing still either, even though the advancements aren't coming as quickly as they used to.
