I view it as sidelining cars to improve public transportation.

• First thing is to eliminate and revise public zoning laws and removing parking minimums. This causes change the slowest but is the most important to start since it will lead to denser population centers, and parking garages can be closer to residence.
• Second move I think is to eliminate extra lanes and trim road widths. This leads to driving being something that takes more focus and is slower. This also frees space for bike lanes and even dedicated bus lanes.
• Slowly phase out free parking across the city. Start with spots directly next to crosswalks so that there is better visibility of pedestrians crossing. Then focus on bus routes to free a dedicated lane when possible. This discourages driving since there's fewer chances you'll be able to park close to the place you are going.
• While this is occurring, you should be introducing public transit as it becomes feasible. More buses or trams, guarded bike lanes, etc.
• MAINTAIN YOUR PUBLIC TRANSIT!! As trains and buses fall into disrepair the number of people willing to ride it will drop off. Also keep the bike lanes and sidewalks clear and smooth.

That's what I've got. It takes decades to break down this infrastructure for new stuff. You also need the to be having accessibility in mind whenever you are thinking about installing public amenities or removing infrastructure.

That will depend a lot from city to city, and also person to person. Some people loathe public transportation, as they see it as something for "the poor". Trading in cars for motorcycles, electric or combustion, is a good step forward, but would just lead to those ultra dense Indian cities.

What works best is not having places you want or need to go so fucking far: school, grocery store, workplace. For me, my job is 30km away from my home, but thankfully I can take a bus. Some people would take buses, but don't, because of: 1- they're overcrowded (because it's more profitable); 2- there's no direct lines that go to where the person wants to go ("low demand", unprofitable); 3- they don't run at the times the person needs (same as 2)

Another user mentions that many drives are less than a mile, for me that's whenever I go buy groceries, as I don't have a bike or anything to carry the bags, so putting them in the car works better.

By making it utterly unaffordable.

Fortunately electric cars are coming, and none of them are cheap.

The downside is you have to explain to an entire class why you no longer deem them worthy of owning a car.

Make everyone use bikes
