It seems to me that an urban car tunnel would be the most likely thing to induce demand: it's useless for local traffic, and is so expensive that it's only going to built in places with lots of latent demand.

Build one and I agree with you, build 10 and that's no longer true. So, the question becomes can you make it 10 times cheaper.

Remember, congestion lowers throughput and surface traffic scales really poorly.
