Didn’t I see this on the Italian Job

From the BBC: German drives down subway stairs
“A German woman in Dusseldorf blocked the entrance to an underground station when she mistook it for a subterranean car park, police said on Wednesday.”
A) It looks to be a pretty large entrance
B) Perhaps it was signed as a car park. According to the article, this is the second time it happened at this location.
C) Perhaps we should let small cars onto underground trains, I mean, we already let bikes on. (Off-peak of course)
D) What would be the fare for a VW Beetle on the Underground?
E) Car free streets … Car-friendly stations?
