Abolish free parking. Free parking is a massive subsidy, usually paid for by poorer people (some who can't even afford cars) to drivers (especially richer, white folks who rely on parking cause they're coming from the suburbs).

Parking should fund bike infrastructure and mass transit, if it's allowed to exist at all. Make parking expensive enough and people will drive less and you'll be able to fund better options. I'm gonna recommend "The High Cost of Free Parking" (even though I've never read it, only listened to interviews with the author).

Other than that, go yell at your representatives if you can. Call them. Go to city council meetings (if you can make it). If you can't, ask someone to bring a tablet with a video call and tell them exactly why you're not there. Tell them you know it can be done better. Tell them you want them to throw out their street design manual and replace it with a dutch one (I think this is may help). Be as absolutely loud and annoying as you can about everything that sucks and take every opportunity to tell people how much better it can be.

Get involved with cycling and transit freedom advocacy groups, if you can. If there isn't anything in your area, consider starting one. Start listening to "The War on Cars" podcast (they did an interview about that book I mentioned), because they also have some advocacy related content. Try to get people in your city or town in contact with the Dutch Cycling Embassy. I'm sure there's some more and I hope other folks also chip in with ideas.

Something something, welcome to the war on cars. (It'll make sense when you listen to the podcast.)

Edit: Oh, here's something a little less aggressive than my ranting if you're wanting to convince non-anarchists: https://bicycledutch.wordpress.com/2012/12/06/who-else-benefits-from-the-dutch-cycling-infrastructure/

Also, do you mind if I quote you? I'm still updating it and I might try to publish it. This is a great quote and it would be great if I could throw it in that section, if you wouldn't mind.

Edit: Oh yeah, watch Not Just Bikes and introduce as many other people to the channel as possible. Never underestimate the power of being someone who absolutely will not shut the fuck up about what is wrong and the fact that it can be fixed.
