This German-language video shows Ronny Wechselberger breaking the world record for parallel parking -- that's sliding into position quickly with as little clearance as possible. He set a new record at 26 cm.
The notes at the video link state this record was set in April. Since that time, Zhang Hua of China broke it at 24 cm.-via Doobybrain
