This is very, very wasteful compared to actual mass transit. A subway network is much more effective at delivering people.

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.

Auto piloted cars could easily reap the "conveyor belt" advantage if they were the only type of vehicle allowed on the road.

Depending on the specific location, there may very well be. Underground tunnels are vulnerable to earthquake-inflicted damage, for instance, and you would want to avoid repair as much as possible.

Similarly, there may be environmental or conservatory reasons not to build tunnels, or reasons related to cost, or obstacles not yet encountered (that last one is less likely though).

The video shows some sort of shuttle using the track. Those could be small busses or even public transport. http://imgur.com/a/Wv8YD In effect, this is a subway system. It's an underground rail system. The major difference is that you have a mixture of public and private passenger vehicles and smaller vehicles.

But can you get a moving block signalling system such that they can follow each other with minimal separation? Until you can do that, a real train will always win at people/hour due to the fact that you can have more people per consist as ultimately the signalling challenges are comparable and you can therefore have comparable separation.

I feel like everything Elon Musk undertakes with his companies is just one huge Mars Beta Test. - SpaceX: Obvious, got to get to space somehow - Tesla: Build cars/machines to run on something that is guaranteed to exist on Mars (the sun) vs. Oil - Gigafactory: How to build batteries 101 - Solar roof: While Earths environment may not be as harsh as Mars you still learn something, and improve solar panel production in…

We'll have to look seriously at living underground on mars. It won't protect us from solar rays on the surface. One of the cheaper ways to protect yourself is to put a layer of rock inbetween you and the sun.

Perhaps if you're building a cellar. If you want to make a 10-story building - even in a virgin terrain, it's a complicated operation.

Not to mention that you need to make the materials such that they resist a huge side pressure, water leaks and so on.

Psychological costs are also costs.

I've always enjoyed this theory. Just one guy figuring out how to take over a planet; no big deal.

In the same way a road offers private and public transportation, a tunnel can do both. Why can't the car be a bus, say?

Hilariously so even. This is basically a subway system, except you have to provide your own seats. All this is succeeding in doing is making Musk look hilariously out of touch.

hilariously.

What we really need to do is to figure out ways that reduce the need for all this transportation. When you look at it from a distance almost none of it makes sense. The only travel that really needs doing is people working with physical stuff, moving the goods themselves around and leisure travel (and that one is definitely not a must but it is hard to make a stand-in experience that is comparable to the real one). Most commuting is - or rather should be - totally useless.
