That's pretty easy for Europeans to say that have never experienced living/working in the US. Everything is much farther and it's not always possible to live near your work. Heck, I worked 30 miles (40km) away from where I worked in Florida and there was no option to live closer. There was literally NOTHING out there except for a little gas station with overpriced gas.
The town I lived in had no public transport and we were at least 60 miles away from anything resembling civilization (like clothes shopping or other things you couldn't find at the local grocery store). Biking wasn't really an option either since the road to work was one of the most dangerous stretches of state highway, in fact about 6 months before moving to Europe a co-worker got hit by a car and almost died. And he was wearing a helmet.
A lot of the US is like that. Not everyone is fortunate (or unfortunate in some cases) to live in big cities where there's decent public transport or it's safe to walk/bike to where you need to go.
And I can see why Europeans don't see it the way Americans do, especially when you have countries like the Netherlands with very decent public transport and bike paths through the country.
I would also like to be able to take a bike where I needed to go, but like you said a lot of places I need to get to are over 20 miles away, and in the winter it would be an absolute impossibility.
