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.
The 52-year-old drove her Volkswagen Beetle across the pavement and into the entrance, where it came to a halt five steps down.
Police estimated the damage to the station at around 1,500 euros (£1,000).
The VW Beetle-Cabrio remained balanced on the fifth step and the woman was able to get out unaided and unharmed.
A local newspaper said the woman was more shocked and embarrassed than hurt.
