Faces were squashed against the windscreen and bodies teemed out of the windows - but that is the effort required to break a world record in a Mini.
Twenty-eight women squeezed themselves into the popular vehicle in London, as 400,000 other people around the world attempted to break world records for the eighth annual Guinness World Records Day.

It took the group 18 minutes to wriggle into position and claim the record for Most People Crammed Into A Mini, breaking the previous record of 27 which was set in Eastbourne last November.
The record-breaking celebration was rung in by 15-year-old Lachlan Phelps in Australia who set a new record for the Longest Note Held On A Didgeridoo (65.66 seconds).
Within the didgeridoo community holding a note for up to 30 seconds without using circular breathing is considered a great achievement.
One of the day's wackiest records was achieved in Japan, where Kenichi Ito broke the world record for the Fastest 100m Running On All Fours.
He completed the distance in 17.47 seconds shaving over a second off his own time, and dreams that one day the Olympics will introduce an 'all fours' category.
Meanwhile in the US, athlete Tone Staubs broke the record for the Most Pogo Stick Jumps In One Minute with 265 in Stamford, Connecticut.
And in Germany, 18-year-old Michael Kopp broke the record for the Longest Duration Spinning A Basketball On A Toothbrush, with the basketball-freestyler managing to keep a ball spinning for 26.078 seconds.
Speaking about the record set in the Mini in London, Guinness World Records editor-in-chief Craig Glenday said: "The Mini is a British icon, and the Mini-cram has become a symbol of classic world record breaking, up there with cream-cracker eating and leaving your fingernails untrimmed.
"And like Guinness World Records, it's a successful child of the 1950s."
He added: "Guinness World Records Day is a chance to celebrate not just the incredible individual achievements but also civic and national pride - whether it's trying to squeeze into the ultimate British icon, the Mini, or an Aussie holding the longest note on the didgeridoo or thousands coming together to perform a symbolic dance, this year it seems to be all about bringing records back home to the people who are most passionate about enjoying their culture and national identity."
