Actually, you can't have a law that enforces common sense because, in a sense, the law enforces nothing. The law sets the rules and the police enforces the law. A law enforcing common sense is vague, which would hardly result in its being voided, but it, like many other laws, would give the police very broad powers, which I doubt you would want. But there are other points here.
One, which applies to most all laws, is where the law is applied or passed. Would you want a national law on this topic or at the state level?
There is usually more than one way to control behaviour, and in this country we usually choose the one that makes less sense. We have a problem with 16 and 17 year olds having accidents, sometimes associated with drinking. We can raise the legal drinking age to 21 but it never occurs to anyone to raise the legal driving age to 18.
