Here is another reason. I can't afford a reasonable sized apartment that can house my family near my work. So I have to travel further. Bikes are great for cities if you can afford to live in the city.
Also, what happens when it snows and you gotta get to work? Snow chains?
You can get chains for bike tires too. I haven't tried it myself but I've seen mixed reviews. Meanwhile somewhere in Europe everyone bikes everywhere in the snow with regular tires because their infrastructure is awesome, snow compactor thing is awesome, and people aren't brainwashed by big automotive.
Not really. Where I live, the bike infrastructure is decent, even though it has its flaws. Right now the conditions are the worst, it's cold, we had a lot of snow recently and even though they removed most of it, there is a lot of ice still. I just have to bike slower than usual, that's all. Last year I remember like 5 days when biking was all but impossible snow was building up faster than they managed to remove it.
biking in snow is possible and common in some places, just need the infrastructure to clear out snow in a timely matter. In some places its quite common to use a bike, even in the winter
Nothing stops you from commuting by bike. My best friend commutes over 40km by bike every day. Due to eternal traffic jams he's not even much slower than going by car, he also almost gets to go in a straight line rather than following highways. Get out of that US centric mindset and realize a lot more is possible by bike than you might think.
These problems are interlinked. So much space in American cities is wasted on parking for cars. Then there isn't space to build housing close to where people work.
