There are parts of the US where the infrastructure and attitude isn't so bad. Not as good as much of Europe, but good enough to make it OK. This is extremely variable, though. I've seen many parts of the nation where I wouldn't dare to bike.
Where I live, for instance, there is a law that requires a percentage of all road funds to be used for bicycle infrastructure. As a result, there is quite a lot of well maintained bike paths that are completely separate from the streets. About 2/3rd of my daily commute route is physically separated from road traffic -- to the point where the only time I even see a car is when they're going across an overpass of the bike path.
In the US, I have heard that the statistics around biking to work every day is that the median lifespan is higher, but the variability is much higher.
I barely feel safe around other drivers when I'm in my own car, a marvel of technology designed to keep me safe.
