What If?

Ars Technica has an article on the proposed tunnels connecting O'Hare to downtown Chicago. They note:

The Boring Company has released details about its proposed system already—it calls the system a "Loop," as in a modified version of the "Hyperloop" idea. (This means there will be a Loop to The Loop—very cute, Chicago.) Unlike the Hyperloop idea, the tunnels will not be depressurized. The company has stated that its electric pods would travel at 125-150 miles per hour. The city of Chicago's press release confirmed that The Boring Company has proposed vehicles that will travel faster than 100 miles per hour.

 Nice idea bu:

1. What if there is a breakdown
2. What if there is a burst water pipe flooding the tunnel
3. What if there is a health emergency
4. What if there is an earthquake
5. What if there is a broken gas line
6. etc

Namely these claustrophobic tubes that are reminiscent of birth canals are not like New York subways, with multiple entry and exit locations where emergency facilities can be brought to bear. This may be a great idea if it works all the time, but we know that such is not the case. There does not seem to be any discussion of these issues.

There seem to be only two points of entry, the beginning and the end. That is a long way to go without any problems. Just look at the DC Metro.
