Live PD

Live PD, in my opinion, is one of the best shows on tv. Maybe someone can clarify some things for me
1- Why is every car in Missouri that is pulled over is not registered or insured, nor does the driver have a valid license? Hell most dont look like they would make it to the end of the driveway without falling apart, let alone be driving on the roadway endangering everyone else.
2-Why do most cars in South Carolina have paper tags that are expired? Also most do not have a valid license either.
I would hate to get into an accident with one from either state, as you would be footing the bill for your repairs, because the driver doesnt have a pot to piss in.
