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.

Lately I've been pointing out that most drives people take regularly are only a mile or two long. It's a hit and miss argument though. Probably more useful for getting people on board with smaller, lighter, cars than getting them out of cars entirely.

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
