Here is an idea. Take 2 lanes of that already existing street. Block them off from cars and make dedicated bike lanes. Then take another 2 lane and make a dedicated bus or tram line.

> It uses existing technology (cars)

A technology that kills a huge number of people and destroys the environment.

> existing infrastructure (streets)

Infrastructure that when uses for cars is very expensive to maintain and a safety risk.

> existing data infrastructure (cloud providers)

This computation not fixed, if you want to use it you have to pay more then somebody else is willing to pay. Its note like an unused road at all. So sure it exists, but its not idle.
