Do you know for sure they were protesting cars, not emissions, not raising awareness for any other cause? It doesn't matter, I'm just curious.

Your complaints about public transportation make no sense. "Public transportation is bad so don't spend money on it." Obviously, if we spent money on it, it would be a viable alternative. I spent some time in Austria this year, a country with excellent public transportation. I could step onto a bus (there was one at nearly every stop about every 10 minutes), be at my destination with no delay, hop off, all without ever needing to show my ticket or talk to anyone. Cars would have been vastly more inconvenient to get around the cities, finding parking takes time, and you almost never have the right of way over other vehicles/pedestrians (as you shouldn't, you're in the safe metal box and they're vulnerable). With effective public transportation, I was able to get out into the Alps, go hiking, and come back into the city without needing to worry about any of the complexities of a car. I could hop on the tram, grab dinner downtown, and be back, without ever getting stuck in traffic. It was so much easier and more convenient than anything I've ever seen living in the US, and I fully don't understand the argument against it. No one is stopping you from owning a car! I own a car, and I won't stop. There are some things I need one for. This movement is about effective public transportation, and there is no reason to be against it except insecurity, and apparently a fragile ego. What's next, antifascism protestors block your way to work and you start wearing a swastika? Being reactionary accomplishes nothing good for yourself. If you're that easily manipulated, every false flag will work on you with no questions asked.
