It seems this discussion comes up fairly often, and the solution is almost always some variation of "make driving too expensive and/or too inconvenient, to force people to use public transit". On the surface that kind of makes sense, using a large stick to strongly encourage change, but I think at its core it misses a huge portion of the problem, which is that bad public transit is 10x worse than just sitting in a bi…
