And that is my point entirely - and your "good of the many example" nails it. So someone steps into the street, and someone does there best to avoid them but still hits them. Two good people, bad timing. Now what. Oh yes, we will let the lawyers and insurance companies sort it out? All that does is benefit the lawyers and insurance companies and not the many.
Our entire legal system is founded on common law - and I think the common man on the street would say that if you can avoid running someone over at all costs you should - and most would agree even in these political times. So why do we need more laws?
