I still don't understand why people (or cities) are excited about the Boring Company when subways and other forms of public transportation have existed for hundreds of years, and are much more efficient at their job (solving traffic).

Boring tunnels, like self-driving cars, offers the appealing vision of saying you can remove a lot of daily misery with this one relatively cheap technology and won’t have to make any deeper changes.
Costs are currently prohibitive and we're suffering terrible, self-inflicted wounds in the form of costs.
The US is obviously bad at public transit, but the solution isn't to build tunnels for cars.
Without the Transbay tube you’d need 2 more bay bridges to accommodate the additional traffic, and there is no way you could fit all those cars on the San Francisco streets, not even if they rebuilt the waterfront highway.
