Whenever I am stuck in traffic, I am thinking about how can we have no traffic jams at all. My idea is similar to this but not in tunnels. I think we can do it on earth. Just have an elevated freeway that is reserved for this type of traffic where road is like a conveyor belt. I hope you got the idea.
