Hey, I also live in a large metro with a great safety record! Yes, because of some serious engineering. Tons of effort with continual upgrades and maintenance.

First of all, you seem to be assuming that I’m saying it’s not doable. It obviously is doable.

But you know, maybe go and read up some of the postmortems of train control systems failing.

And easy _compared to_ vision based systems? Sure! But that’s not even close to the same as “it’s easy”

> And you say it’s not metro but people here are acting like the Tesla loop is “metro” and can compare/be better/cheaper then real metro by “just have multiple tunnels”

I do not know what point you are trying to make here and I’m not sure you do either.
