On average it takes 16 seconds for men to manoeuvre into a parking space, compared with 21 seconds for women.

(Scientists from Ruhr University in Bochum, Germany, found men were better at driving both head-on into the space and reversing into it.  However, the biggest difference was in parallel parking, where men were found to be five per cent better in their handling and positioning of the vehicle. Okay men – you win! (Just in time for the self parking car.))
