Invariably, once Avidor starts posting his propaganda campaign, he won't stop until he spews his entire spiel.

This latest rant falls under the category: "PRT projects failed in the past, therefore PRT can never succeed in the future". Avidor has recently latched onto the Denver baggage system because it failed so spectacularly, even though the Denver baggage system has nothing to do with any PRT design I've ever seen. But Avidor doesn't care if it's relevant -- as long as he can use it to scare people off PRT.

Even if the Denver baggage system is considered PRT (it's not), it's still a ridiculous argument! If every technology was killed after the first few failures, we'd still be riding horses!

PRT has nothing to hide. Past failures are well documented at the Wikipedia PRT page. The reasons for the failures run the gamut: poor design, poor engineering, economics, politics - all things that can be fixed.

Go ahead and decide for yourself.
