At the top of the Champs Elysees is the Place de l'Etoile, which is a huge round about around the Arc de Triomphe. People entering the round about have right of way, and it's quite terrifying. After a while, my technique was to press the gas pedal to the metal and close my eyes while entering the round about, and try to open them early enough to avoid crashing into an incoming driver using the same technique as me. Still alive to tell the tale.
