Do they stop running the tubes or buses if enough people decided to
walk. I can't see how this helps the environment.

Directly: the train/bus doesn't need to use energy to accelerate 80kg of
you every time it speeds up, nor to raise 80kg of you up any hills it
may climb.

And taxis wouldn't have to make the trip at all.
