I have a Romanian friend who left his country for the first time when he got a grad fellowship in Paris...he wound up in his rental car in the huge ass circle at Place d'Etoile (like 8-10 lanes around Arc de Triomphe) smack in the middle of rush hour, and drove around and around and around, unable to get out of the innermost ring, until the car finally ran out of fuel. He just opened the door, got out, and walked back to sanity through the pedestrian underpass.
