Is there any reason to think they will be able to? They are just going the same thing as everyone else but started later. Another player might lower costs slightly but not much.

I don’t believe they have advanced the field in any way. They didn’t really have any solid ideas, just the idea that it would be really cool if tunnelling could be made cheaper. Surprise surprise, it’s actually a highly advanced, mature field and there wasn’t actually any low-hanging fruit for inexperienced startup guys to disrupt…

The only thing they’ve done with their Vegas tunnel is to make it cheaper by making it too small to have proper emergency egress, but they can get away with it since with just their chauffeured Teslas going through it only fitting a few people each (making the system extremely low-capacity), they can’t really fit many people in at once, and it’s short enough so combined that makes it not that much of an issue.

In the newest section of the Vegas tunnel they have now only built a one-way tunnel instead of a tunnel for each way, making it cheaper again but low-capacity to a basically comedic level.

Slow and steady progress. They’re just about to go big in Vegas, with tunnels the length of the strip.
