I'll add to that.
There will always be some people that drive recklessly or do bad things IN SPITE of said "laws". For those who act in a decent manner by default, the "laws" (opinions backed by the threat of violence) are redundant. It also creates an incentive for the state to revenue collect and avoid actually fixing a problem.
It always makes me laugh when I see a sign that says "$500 Fine for littering", as if some jackass that is going to litter is going to care. There is always litter on the roads, so we know that doesn't help. The reason people do bad things is because they don't care. The best deterrent for stupid people doing disagreeable things, is social pressure such as ostracism and better parenting to help people actually achieve adulthood.
Very well said. Laws don't do much to alter the behaviour of those who were already going to behave well. It's a redundancy, as you said.
And laws won't stop those who are going to behave "recklessly" either.
