Men drive better when they have a woman passenger, according to new research.

A study published in Men's Car magazine in Germany found most men drove more carefully when they had a woman as a passenger sitting next to them.

Of 500 men and women drivers tested, 65% of men were found to change their driving style when a woman was sitting next to them - 44% saying it was because they tried to drive more safely.

The same survey showed women took little notice of whether they had a man or woman in their passenger seat.

Some 71% of women questioned said they did not change their driving style if a man was a passenger
