Mr. Anonymous: You are quoting almost verbatim from the Avidor creed, right down to his buzzwords like "faith based transit". So you are either Avidor himself or one of his apostles.

But, anyway, who says it is irrelevant -- the point is, this is the same tired old message that Avidor has been pushing for years now. These points have been discredited countless times on dozens of forums, but he remains obsessive about continuing to spread them, like gospel.

If you want these types to go away, just challenge them to a debate on a technical topic, like PRT safe headway. They'll spout some ridiculous talking point and then disappear with an excuse ("I don't have time to debate this crap"). I've seen it so many times I can almost recite it by heart.

Anyway, if you don't believe me and want a neutral assessment on PRT, once again I suggest you take a look at the Wikipedia article. There is a very nice technical summary there, along with many links to the history of PRT development.
