Ahhhh .... anectodal evidence trumps all. OK.
You can find an exception to nearly every safety law. I once saw a video of a woman looking both ways before she crossed a street being struck by a bicycle riding on the sidewalk.
I suppose that video directly contradicts the claim that it is safer to look both ways before crossing the street.
You are amazing, I'll give you that. You issue a proclamation that everyone doing the same 'safe' speed limit would be the best option. You are shown real-world evidence to the contrary. You then claim that it's anecdotal! What happened to the utopia created by your safe speed limit and total adherence to the law?
Is it one example? Yes. Is it anecdotal? Perhaps, but the thousands of cars on the road in question is a healthy statistical sample. Why do you refuse to concede that the film, its content and outcome may call your viewpoint into question?
Your sidewalk example is irrelevant, by the way, so no response required.
