The tunnel will be unsuccessful because it'll be too successful? People won't want to use the tunnel because too many people will use the tunnel? If Musk reaches that point he'll probably already have won. I think the point being made here is that ingress/egress imposes such a significant bottleneck that total throughput will still be low, and very few people would actually be able to benefit.

>Somewhat counter-intuitively, the answer to that is often "no", due to induced demand[1]. I see what you mean but couldn't you raise the same objection if somebody wanted to, say, create a new subway system or something similar? More people in the new transport system means fewer people in cars on the streets means induced demand... I don't see why this particular project is different. >I think the point being made here is that ingress/egress imposes such a significant bottleneck that total throughput will still be low, and very few people would actually be able to benefit. I agree with that, it's also a problem with hyperloop. It seems like Musk's vision of the future is great if you're rich, not so much if you're poor.
