I think the public will, and have a right to, judge any spending of current or future transportation infrastructure dollars on "how does it move more people more effectively"....after all, the new revenue tools are being sold on the basis that the money is needed to boost public transit infrastructure.
As I have stated (boringly repeatedly, I am sure) a $1.2B spend to get 5 more trains into Toronto and back in the transit corridor the Big Move described as the second most dense in the region, is a pretty awful return on spend and that will make the selling of future taxes (which is what us old folks called "revenue tools") to a jaded public very difficult indeed.
