> while you can walk and cycle without any of those things.

A few years ago a driver making a right-on-red bumped me in the crosswalk with his car. It was reckless but whatever no harm no foul. But then he got out, incorrectly thinking he had the right of way, and demanded my "papers." He was incredulous and furious that I didn't have insurance papers to show him, or thought I was refusing to. He ended up calling 911 about it, though they didn't come.

Ever since then I can't get some questions out my head. Is that really how he thought it worked or was he just flustered? Do other people think like this? This was a middle-aged guy in a suit in a major city's business district, so presumably some sort of professional. Is he good at his job?
