Trivia: driving on the left

Until Sunday, September 3rd, 1967, driving was done on the left-hand side on roads in Sweden. The conversion to right-hand was done on a weekend at 5 p.m. All traffic stopped as people switched sides. This time and day were chosen to prevent accidents where drivers would have gotten up in the morning and been too sleepy to realize 'this' was the day of the changeover.
