If he could combine his hyperloop theory with the existing underground systems around the world to make them more efficient etc then hes on to something."
Many existing underground systems are already running multi-100 capacity trains every 3 minutes or so. How frequent do 8-passenger cars gave to run to compete with that? A vastly bigger and more complex network might do it, but not just a minor expansion of existing networks. I could maybe see it working with smaller trains if stations had passing places so other trains could pass through if no one needed to get off there and there might be smaller trains on the platform loop waiting and ready at all times. I could see rush hour getting interesting though.
