At the risk of being näive, Why Tube trains are still a thing?

I want underground mini buses, optimizing their stops to the passengers' inside. Most of we passengers go to hub stations.

Tubes are like a 100-year old tech without remarkable changes.

Capacity and dwell time.

27 (soon to be 30) trains per hour on the Jubilee line for instance, hundreds of people can get on and off each one.

I don't know why I was downvoted for just asking a question.

I don't get it. Suppose this scenario:

- Instead of big formations, replace each wagon with an electric minibus. - Instead of stopping in all stations, each minibus stops in, lets say 3 or 4. - Each passenger checks into the bus dinamically assigned to their stop. - Minibuses can surpass each other.

You have less dwell time, each ride is reduced to one third of the time.

Your capacity drops dramatically, by at least an order of magnitude if not more. The Jubilee line can do 30 trains per hour, 875 people per train is 26250 people per hour. Say an average minibus can hold 26 people, you'll literally need a thousand busses an hour to move everyone. And yes it all runs at capacity especially during rush hour.

Lets call them buses instead of minibuses and each one has the same capacity of a wagon.

Instead of 10 formations of 6 wagons you have 60 buses.

You have same capacity and one third of traveling time per ride.
