IS IT OK TO LIE ABOUT BEING MARRIED TO GET A LOWER AUTO INSURANCE RATE?

First of all in the state of Missouri they check to see who even lives in the residence and I have had to pay higher premiums because of roommates that did not even drive my car. Who is this agent? yes I disagree that married people are safer drivers as are women. How often do you see a woman driving a SUV while talking on the phone, putting on makeup with a busload full of children is that safer??? Also I have known of several couples getting into arguments and one storms out and is mad and then ends up in an acident and even getting killed. Even thought this os not legal I dont think what they the insurance providers are doing are so legal either. We all need to ban together against them!
