Danish vs. American culture - bus ride

So here I am in Seattle – loving it! Well before going here I really had an idea that Americans are self-conscious and arrogant (sorry). I had never been in the US before and therefore I was really excited about everything.

I have only had few American friends before coming here, and they seemed a bit precocious.
So my impression of Americans was more or less what I have seen in the television and experienced with these two American guys.

Let me just say, I was positively surprised when I first got here

In general Americans seems so open, positive and helpful. Just few days ago I was taking the bus and ended up in the wrong place. The area was dark, cold and the streets were empty just like a ghost town or something. I asked the bus driver for directions since I had no idea where I was.
Instead of just telling me where I was, this bus driver said “a girl should not walk in this area alone”, then he turned around the bus (it was empty except for him and me) drove back to another bus stop further up the street, to make sure I would get on the bus and return safely (and with a bus going the right direction).
If I had been in the same situation in Denmark the bus driver would maybe take some time explaining me were to take the bus from to go back, and maybe even point it out. But never turn around the bus, and follow me in to the next bus to be sure I would return safely.
This is not because all Danish bus drivers are cold-hearted, but in Denmark I guess we just expect adults to take care of themselves.
I think this is a very positive culture shock - so different from Denmark!
