These tunnels could solve the traffic problem. That is the whole point. They can be stacked to great depth to get traffic congestion to zero. People are willing to pay for this and it is only our ignorance and stupidity getting in the way of at least trying. The point of cities is that one has a huge number of people you could potentially interact with. With horrible traffic, this is not the case. With mass transit, you can only go certain places at certain times. Just call a tunnel with automatic pods in them mass/public transit (that is what it would be) and fell good about a better future for all of us.

> They can be stacked to great depth to get traffic congestion to zero. No, they can't. How do you handle vertical circulation? Also, the capacity of highways is absolute rubbish compared to trains. I've run the numbers before--you'd need about 10 times the number of tunnels with Musk's Loop proposal, and about 100x the number of stations to get the same kind of vertical throughput as you would with regular subways. > Just call a tunnel with automatic pods in them mass/public transit (that is what it would be) Loop is essentially (as I've said) personal rapid transit. PRT is definitely public transit, but every PRT system has generally found that the "mass" part is rather hard to achieve. The problem with this sort of thing is that it takes energy out of proven, working solutions to instead build technology that consistently hasn't lived up to promises. I might feel better about it if there were serious discussion as to why this system is going to succeed where others fail, but there has been absolutely nothing of that sort.
