Yeah. I also thought that the tunnels were too small for a subway (because one of The Boring Company's "innovations" is to drive costs down by digging smaller, shittier, and more dangerous tunnels using existing technology). However, there are subways in London that have even slightly smaller tunnels. You could absolutely lay down some tracks in there and have a functional subway. Giving it to Tesla to run a taxi lane for who knows how long was just a choice.

Also, from what I found out, the Loop is going to continue to fuck over the residents, because the expansions are going to have WAY higher fares. I think right now, the Loop is $4.50 for a day pass. As a point of comparison, a New York subway ticket is $2.90, so one round trip would be more expensive than a day pass. That makes the Loop sound great! ...until you realize the prices are kept artificially low to make it seem that way. Future plans for Loop service would cost upwards of $12 a ride outside of the convention center and resorts.

Also, as an aside, something I don't think gets brought up enough is that the Loop proves that Tesla's self-driving cars are a scam. Even on a close course, indoors, built to whatever specs Tesla could possibly want, the cars need human drivers.
