Royal Wedding Blunder: Queen Elizabeth II's Car Door Mishap

A near-miss during the 2011 royal wedding of Prince William and Kate Middleton involved the late Queen Elizabeth II. Upon her arrival at Westminster Abbey, the Queen's car mistakenly stopped on the wrong side of the pavement, prompting her to slide over to Prince Philip's side. An etiquette expert identified this as a protocol faux pas, although she speculated the Queen might have had a personal reason for the altered exit.

Adding to the wedding's unique moments, Kate Middleton's bridal appearance also deviated from historical norms. She chose to wear her hair down, a decision that went against a 350-year-old tradition for royal brides to have their hair up. Despite these minor breaks from protocol, the wedding was watched by over 162 million viewers worldwide, and the couple now has three children.
