Driving in Germany

Arts_Girl: So, Rosa, tell us about this video.

Rosa: I found it online... Axel, Birger, and I were in a car chase with Randy. Apparently, some people were fed up with speeding in that area, so they decided to put a home-made speed hump in the area. You don't have to speak German to get the point.

Arts_Girl: Wow! So what happened?

Rosa: Well, we managed to teleport to a different time before we were all killed, but we lost Randy.

Arts_Girl: Who was driving?

Rosa: Birger.

Arts_Girl: Why didn't I guess?
