First time I read it wouldn't be an evacuated tunnel. Next thought of technology it could use then then jumps to maglev-like technology; Imagine a Tesla vehicle (or others) that can hop onto a network that brings the vehicle onto a maglev system, reducing friction (and other elements wouldn't really effect it, especially if you decided to put a canopy over it) ; Anyone else realize he may have dropped a hint in this video (http://video.ft.com/v/1974478965001/Elon-Musk-from-electric-... ) that we might see flying cars?

You'd need on-ramps, where a minimum speed is required before merging with the main line, and of course you'd only build on/off ramps at major hubs. The only issue I see being you're not using tar then, and therefore costs of raw materials would be higher, at least initially, and would likely last longer than tar.

Being cheaper than highspeed rail could fit into this equation because its the vehicle owners paying for the vehicle, and no trains are being build for it - so actual money going into the system, the synergies that would exist, might be greater - though putting it how he does is creating lots of attention. :)

Maybe the hyperloop refers to a an on/off ramping system, where you get accelerated to a certain speed... Fun speculating. And time for tea and breakfast.
