June 20, 1791 in Tuileries Palace, Paris:
“Come on! We have to go!” the king shouted.
Dorky and derpy as always
“We’re going already,” the coach’s driver said, annoyed.
“Are we almost there?” the queen asked, leaning forward.
The big hat isn't helping you here, Marie.
Especially since you're just using it
to act like you have a big brain.
“Man, we just left! What are you smoking?”
“Excuse me?” Marie Antoinette exclaimed. He better not-
“You’re excused.”
“W-why you-!” Marie vowed to slap the chauffeur at the next stop. She jumped up and down in her rage. The carriage began wobbling precariously.
The carriage slowed to a stop. The carriage had probably stopped at the first town on the route, Marie thought. That meant she had enough time to slap the insolent driver and jump back in the carriage.
She had the power to do it, and she would. Nobody insulted the queen and got away with it!
Five minutes later, she had come to a decision. Marie jumped out of the carriage, ran to the front, and slapped the poor carriage-driver so hard that he fell off the horse.
The horse immediately reared up and tried to bolt for freedom from the madwoman. In the process, he trampled all over Marie, leaving her stranded and injured on the road. He then attempted to run away, while the carriage behind him broke down. The ceiling itself crushed Louis’ neck.
The Ancien Régime was no more. The old monarchy had died with the attempted escape of the royals.
The Queen’s Saving Grace by Maximilien Sartre in 1832:
“Queen Marie Antoinette had, somehow, got the idea to visit the common people of Paris. While she chose a terrible vehicle to ride in (who visits commoners with a fancy and rich carriage?), it was this saving grace that perhaps preserved the monarchy.

There are, of course, those who dispute this. People say that King Louis XVI was attempting to flee with his family... Obviously, they were wrong. Marie and Louis had wizened up to their flaws.
The carriage with the royal family was found on the streets of Paris with some of the wheels broken. They died from a malfunction. The people of Paris, grateful that the royals had finally decided to try to do something for them, actually showed up to the funeral for King Louis XVI and Queen Marie Antoinette.
Somehow, though, Louis-Charles, the Dauphin, had survived. He had been curled into a small ball under the wreckage, though the king was reportedly sheltering the boy with his own body. (Of course, these might just be embellishments, but...)
The people of Paris descended on the carriage accident and pulled away the rubble. The small, frightened boy had hugged the first person he had seen, endearing himself to the masses...”
