Yikes Smilingcat, I assume you weren't aware that "rice burner" is a racist term...
(I do hear what you're saying, though, about branding a whole group of people with the very noticeable actions of a few.)
W/R/T NYC riders though, there's another thing going on here. I don't think anyone who's never visited NYC and seen the traffic for h/hself, should say anything at all about NYC traffic. It's a thing unto itself, markedly different from traffic in any other city I've ever seen (including Paris, Milan and Bologna, just to pick three where the rules are very different from, say, Washington DC, Atlanta, south Florida, Chicago or San Francisco). I think every locale has a set of unwritten traffic rules that supersede the written laws (but it's been way too long since I've driven in southern California). "Outsiders" learn these rules at their peril, but more to the point, aren't really qualified to discuss their niceties.
