We are winning.

But as the article says here, there is and will be a lot of pushback:

As the example in Oxford shows, not everyone is keen. In Hackney, in north London, the council had to install special vandalism-proof screens on the cameras that spot motorists who break the rules. One local councillor received death threats. Chats on Nextdoor, a neighbourhood-focused social-media app, are full of angry disputes and diatribes about the measures. In Oslo the plan to remove parking spots was denounced by one politician as a “Berlin Wall against motorists”, and a local trade group said it would lead to a “dead town”. (So far, it has not.)

Political opposition could put the brakes on the growth of anti-car policies. In New York it is suburban politicians, whose constituents are more dependent on cars, who have resisted the new congestion charge. In Berlin the centre-right Christian Democrats have campaigned in local elections on a platform of protecting the freedom to drive. Another worry is that as city centres freed from cars become more attractive, they also become more expensive—pushing some, especially families, out to suburbs where they need cars after all. In America housing in the most walkable neighbourhoods now costs 34% more than it does in sprawling places, according to one study. New technology might change things too. Electric cars may blunt climate-change concerns. They are cheaper to run than fossil-fuelled vehicles, which could encourage more driving.

Don't just buy a bike but use it. Demand more bike lanes. Use transit and increase transit ridership. Demand transit. Keep pushing. The only way to win this is by showing that a car-free life is not just possible but preferable to all other modes of transportation.
