In 40 years there has not been a single failure of automation I am aware of leading to a death here in a city of millions. This is a busy metro not some tiny thing with a couple stops

40. Years.

So yea it is a solved problem from the perspective of living in an area with a large metro that has been fully automated for as long as I’ve been alive with very few failures and zero of these “serious issues” you think happen.

They were able to do it here with 40 year old tech, it should be easier and cheaper to do now

And it is easy when you are on rails in a controlled grade separate environment compared to automating cars/whatever Tesla is failing to do with cameras alone

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”
