It will also not compete with rail or air because of that exclusivity. As far as govt inspections and sign off go, I bet that won't be a huge problem. This is a very cool use of technology with the possibility of becoming cheaper over time. I'm sure there will be a lot of talk about safety, but that's necessary right now. Identify and overcome the problems. It's not like they will be trying to cut corners on this, they want it to work well.
