Yes, there is a Guinness World Record for "the tightest parallel park." And Han Yue beat it this week; sticking a Mini Cooper between two other cars with not more than 3.15" to spare. Also, he did it in one motion.
The spectacle went down at the China Drift Championship in Chongqing on November 14th, for your record-book reference.
TopGear says Yue also held the record in 2012, which was beaten by somebody named Brit Alistair Moffatt who slid into a space with 3.385" of room left.
Who's gonna try to beat him parking in town this weekend?
