I can't help but feel that many people who now work remote and therefore don't need to commute suddenly are all for moving to mass transportation...that other people will use to get to work.
You could take from the hotel tax to pay for trains, or build bike paths that go alongside or orthogonal to roads.
If you go to people and say "cars or trains, pick one" of course cars will win every single time. You want to say "here's a solution to a problem that doesn't make your life worse". Which is why many of the newest suburbs and developments have the best bike/walking options - they're being considered from the start.
There's also the social design component: making driving uncomfortable increases the relative comfort of public transit, meaning people would be more likely to choose the latter over the former, improving the chances of a critical mass of public transit utilization.
