My clarification on Shortreed was merely intended to point out that his credentials are often overstated and on occasion misrepresented by various media in the context of his authority in matters of higher-order transit planning. I'm sure he was an excellent Professor of Civil engineering, and has likely made many fine contributions to his field. However, decades-old research on a tangential discourse to the one currently being discussed is not particularly relevant in my opinion. I feel it would be more accurate and applicable to cite Shortreed's credentials as a dedicated citizen, and passionate and concerned opponent of rail transit.
I don't know Mollison personally, but based on what is available publicly with regards to his involvement with TriTag, I see no reason to assume that his advocacy of light rail is predicated on anything but a strong understanding of the Region, its current and future transit needs, and a clear sense of civic pride and duty.
It's also surprising - suspect, even - that you've chosen now to put so much weight on academic credentials, considering past instances in which you have flippantly dismissed current research on a number of issues as "some asshole. . . quoting some random study from some randon study from some are that is random to here." Why the sudden change of heart?
