My husband is a retired police chief, his tip is to cut out the address line on your car registration and proof of insurance. Just cut out the line with the house number and street. That way if you car is stolen the thief only has your name and city you live in. Most of us leave the garage opener in the glove box with these papers making it easy for the thief to get into your house, so easy since he has your car and knows where you live and knows you are not home. If you should get pulled over by the police there is no problem, it is perfectly legal to cut the line out. The laws only require proof of registration and insurance. The police will run your drivers license and verify with you your home address.
