I think your second idea is closer to what I think matches the things known about Hyperloop. I am convinced that electric (or hybrid) cars that self drive along beacons is the obvious next step in human urban transportation. These follow loops, like bus routes, that will pick you up when you get to a location along the loop since you have requested it (e.g. phone app) and drop you off at say a station, or another loop intersection where you can get into another loop vehicle, a loop bus or train at a scheduled and managed time. It can send the right size and amount of vehicles out of the depot into loop depending on how many people want to get on during a cycle, it can park the electric vehicles to charge at the right time. To the user it's a matter of saying 'I want to get to the conference at 9am' and the system will tell him what time a car will pick him up at his chosen pickup point.
