I really dislike cars and being around cars. They are noisy. They ruin the air quality of a city. They take up massive amounts of space through parking that could be better used. They force the public to subsidize car owners. They kill people through both air pollution and through collisions. They dominate a city's life in an extremely unattractive way.
I base a lot of my existence around avoiding cars and living in places where I can have a pleasant walk without having to deal with traffic. To the point where I recently moved from Chicago, Illinois to Portland, Oregon because Portland is a much more pedestrian friendly city. And it shows. You walk around the city and it's actually alive and working.
In Portland, people don't have to have their children on leashes because every street isn't a 4 lane highway with constant traffic that is disrespectful to people's space. People are strolling down the streets and wandering into businesses. In Portland drivers slow down and wave you across the street instead of swerving around you at 40 miles an hour.
In Chicago a common occurrence was for a car to decide to make a red light, so they would make a turn into a crowd of pedestrians who are crossing the street and "shoot the gap" without slowing down, with maybe 3 feet of clearance on either side. People would open doors without a second thought and door bikers. Trucks would make dangerous turns into bikers and frequently kill them ( A young woman was recently killed this way, and I once had to jump off of my bike and drag it onto the sidewalk to avoid being run over ).
Cars drivers seem to enter this "magic circle" where it's fine to do dumb and extremely dangerous things because you are driving. When you are in a car, all behavior is acceptable.
Decide to teach the biker a lesson by turning into them? They won't charge you with anything.
Swerve into a crowd of pedestrians? It's fine normal behavior.
Make a blind turn into an alley and have to slam on the breaks to avoid running into a pedestrian? Totally A-OK chief! Great work!
As has been pointed out elsewhere, a lot of European cities do not have this problem. When visiting France, I went to the city of Strasbourg where they have a very nice little "park and ride" system where you park your fume-spewing, space-taking machine and park it in the PARKING AREA, instead of letting you drag it into their beautiful city.
strongtowns.org has a lot of great information about how the US road infrastructure is, to put it bluntly, a dumb and bad experiment that has failed.
