I genuinely believe that car owners could be tricked into supporting FuckCars policies by a very crafty politician/campaign. It would work like this:

1. Proclaim your love of cars. Loudly. "I want to make our city the best city in the world for drivers!"
2. "What are the biggest problems drivers face today? Traffic and parking! Therefore... We need to open up roads and parking spaces..."
3. "And that's why we're going to cap the number of cars that can enter downtown. With increased public transit, we can free up these roads for drivers! That way: more parking, less traffic, a better life for drivers"

Do the same thing for bikes:

1. "These bikers want to share the road, but studies have shown that whether you use sharrows, plastic bollards, it doesn't matter: people still get hurt.
2. And here's the thing: when a car hits a cyclist, it's bad for everyone, including the driver. Nobody wants to hit a cyclist. But the sad truth is that it might just not be possible to share the road
3. "That's why I'm proposing that we make some roads car-only, to protect cyclists." [Crowd of drivers cheer, and you quickly say:] "Also we'll make some streets bike-only, for the same reason." [And then when you get in office, just be like "Yeah the highway is for cars"]

I'm available for speeches if anyone's hiring
