- reallocating road funds (away from driving and toward busses/rail/bikes)
- tax car infrastructure appropriately, presumably higher
- reduce parking minimums
Not that I'm against these, but they will surely make driving worse.
What makes driving worse is the presence of more cars. This can be partially mitigated by piling money into road infrastructure, but infrastructure is a band-aid on a problem created by more people choosing to drive.
What makes driving better is the presence of fewer cars. There's really only one way to reduce the number of cars on the road: build good alternatives to driving. If you love driving, you should be the strongest champion of public transport investment.
Here's a good summary of one case of a small town dealing with absurd parking regulations... https://www.strongtowns.org/journal/2017-11-22-how-parking-m...
And just to add my own recent anecdote... we visited southern Italy (Puglia) last month. Most of the towns have zero traffic* zones (ZTL zones) in the historic centers. In all of them, there were either ample metered street spots just outside the ZTL or small pay lots a short walk away. As far as I could tell, as a tourist, it worked well - the downtowns were vibrant with lots of foot traffic.
* ZTLs allow local traffic and handicapped transport within certain guidelines.
