Some people appear to treat their cars as a home from home.
Doing their make-up, singing loudly and it appears, sometimes, tucking into their breakfast.
Astonishing footage published by a cyclist on YouTube appears to show a driver eating their cornflakes while overtaking bikes on the streets of Edinburgh.
The footage was shot by a YouTube user calling themselves 'Raging Biker', who says he rides 'around 5000 miles a year' while commuting to work.
The video was posted to the site along with the following description: "I guess if you are hungry then why not eat a bowl of cereal as you drive. How did he do this?
He must have planned to exit his house, climb into the car (no hands?) with a bowl of cereal and milk....who does that???"
The footage appears to show the driver holding a bowl of cereal and steering using one hand.
The cyclist then catches up with the driver at the lights and the resulting clip shows them driving with their breakfast bowl in their lap.
In response to the video a spokesman for the AA said: "It's pretty stupid. It's unbelievable."
"For some people, their car in a way becomes their home and they behave in such a way that they would in their house."
"People just don't seem to have the willpower not to do things they know are wrong, like turning their phone off or not eating a sandwich while driving."
