So 4, maybe 6 if you add Atlanta and Seattle (both of which I doubt have a majority share of transit), out of over 300 cities (or equivalent) with 100k+ people.
I live in Cambridge, MA (attached to Boston and sharing one of the top 5 transit systems in the US). We have one car per driver and expect to maintain or exceed that ratio for the next three decades as we can’t afford to spend the increased time needed to do all trips via transit. Or even transit plus ride-share.
That's exactly what needs to be fought. A bit of carrot, a bit of stick
What I mostly see are plans to nerf the utility of the auto, in order to make it competitive with the current utility of public transit.
Me, too. For instance, I'd like to see some modern effort to reduce the effects of the tinnitus-causing screeching of rail cars on the MBTA. For daily commuters who take particular routes, the noise pollution is a serious issue.
For another example, I'm reasonably sure regenerative breaking is not a thing for the light and medium rail, (might be for the silver line) because those systems are old enough designs that efficiency wasn't so much of a concern. Rather, I recall hearing they use big resistor packs to turn speed into heat, and maybe stink up a station when they fail.
