If I got into an accident and someone asked for my license, I'd outright refuse. They have no need to have my license in their possession. You'd get my insurance information and that's it.
I tapped the rear of a lady on an offramp this winter while coming back from fishing.. One of those people who is turning right on a red, goes about 3ft then stops again. I tapped her at maybe 2-3km/h. Well the we pull over and she calls the cops, then refuses medical treatment, lol. So I get charged with careless, court date is in a few weeks. Even the cop was shaking his head....
