Cycling in the US really is more dangerous than in Europe. I see two main reasons: 1.) Drivers are not aware of cyclists and don't know how to deal with them.

Cycling in the US really is more dangerous than in Europe. I see two main reasons: 1.) Drivers are not aware of cyclists and don't know how to deal with them. When I cycle on roads with considerable car traffic, it regularly happens that cars drive dangerously close to me or that they cut me off. In Germany, drivers know what distance they should keep and to look for cyclists when turning. 2.) The condition of the streets is incredibly poor in the US. Potholes are a real problem, not just for cyclists. Some ptholes in San Diego are a foot deep and this is of course super dangerous for cyclists. I've never seen potholes like that in Germany.
