If you snack at the wheel, being distracted from the road isn't the only thing you risk.
Scientists have found a range of illness-inducing bugs lurking in car interiors - and eating while driving could be to blame.
Microbiologists from the University of Nottingham swabbed a selection of vehicles and discovered strains of bacteria including staphylococcus - which causes infections - as well as one that could lead to E.coli.
And a survey revealed that while three in five motorists munch on the move, only a quarter clean their car at least once every three months. More than half admitted dropping food into the seats or footwells.
"It's worrying to see just how dirty people are letting their cars get," said Kate Rose from classifieds site Carfused.com, which commissioned the research. "With people using their cars to transport children and friends, they should take better care of them."
