Part of the problem is in america if you want to bike that far, you probably have to take some route designed for cars. It’s very stressful and in many cases very risky.
Local climate is a problem, too. It’s not fun to bike to work some days when it’s very hot and humid, and then in the other half of the year, deal with freezing rain.
This is a valid comment. Many times, when the US makes "cycling infrastructure" (scare-quotes intended), it's just awful: painted lines on a busy, dangerous road, or at best a path immediately parallel to such a monstrosity. Little wonder people don't want to ride a bike next to a bunch of giant SUVs speeding at 75mph.
And it is true the weather in many US cities tends to be less mild than in Amsterdam, but that can be worked around with proper clothing.
I am vehemently on the side against cars, but I will wholeheartedly refute that our summer weather can be worked around with clothing. It's far too hot and humid for that to do anything.
When I lived in a hot American city, the saving grace was that at both office jobs there was a shower available. After breakfast I'd stuff my work clothes in a backpack, bike to work in shorts, take a quick shower, and arrive at my desk the most clean and refreshed person in the department.
