As a Dutch person living in the US, a big difference is also that almost every driver in the Netherlands is also a cyclist themselves. In the US there is this almost cultural divide between drivers and cyclists where it becomes part of people's identity. In the Netherlands most people will just choose their mode of transportation depending on the specifics of the trip.

In practice this means drivers tend to do a much better job anticipating cyclists, e.g. by checking for cyclists before making a turn.
