Does a virtuous Buddhist indicate when making a turn and no-one (else) is watching?

It’s a question about the balance hetween adhering to law but also not becoming ridiculous about it. I hope it’s not a ridiculous question. ———- I am adding a justification for the validity of this question: violating a law in principle is suffering related, if not for getting caught by a hiding police officer, then because of moral shame anyway. so the question is about whether getting too pedantic about the law is silly (silliness leading to suffering, I presume.) For example, a traffic light in the middle of a desert — who would obey it but a fool?
