I totally disagree - men are far worse! My husband Mike has a new BMW and it's like a skip. His excuse is that he 'lives' in his car and it's his office. He eats big macs, kentucky fried yuk and god knows what else in there, as well as smokes and throws his rubbish on the back seat - it's gross! I on the other hand have an immaculate car with no crumbs dust or anything.
He parks as close to the door of a supermarket as he can and consequently has been hit twice already - I park at the other end and walk! And I know LOTS of men the same as him. It's not a male/female thing it's purely whether you're a car person or not.
