rail is seven times more energy efficient than buses.

I think he might be quoting a best case scenario, ie fully occupied transit comparison, then spreading the energy use out per passenger, maybe then, but the trains and buses run when they're not full as well, surely that would even out the difference in those peak times more.

Shit yeah! Theres a growing number of conversations starting to happen over here in Perth about using the river more for public teansit as well. Not sure about energy efficiency, but very cool.

rail is more comfortable

As a fan of buses this is a point that has to be conceded, but trackless trams are also an option.

Those old school double decker trams at the start of the video were interesting pieces of kit!
