For germany, there's a study that estimates that up to 30% of a flats rent in densely populated areas is directly or indirectly caused by car-centric planning. And if I just go round the block and estimate how much space is taken by (toll-free) parking and car lanes, I can quite well imagine that this number might be on the high side, but not entirely unfounded. Just half a block from my flat is a road that is double lane, at intersections 3-4 lanes including turn lanes in each direction, each direction offers a parking along the road and in the middle are two parking lanes 90° to the road. The parking space allocated would be sufficient to create a full house the entire length of the road. All that road space is built and maintained by the city, which receives neither vehicle tax nor any petrol taxes or any of the taxes that car owners pay.

I'm not generally opposed to people owning cars and using them. I'm opposed to people offloading the costs and space requirements of their private property onto the community.
