Yes, all those things. Except on cost, at least in SF, MUNI is free for children.
We mostly drive wherever we need to go, especially when it's all of us. But if we're going to a Warriors game, we always take Muni, at it's more convenient (and free for adults too if you show your ticket).
Also, it's generally faster and more convenient (and fun) to get to Chase Center via Muni than driving. Getting back is tough both because this is peak Lyft/Waymo demand as well as peak Muni demand.
