You're right! I come from a very bike-dense country (The Netherlands, we have more bicycles than inhabitants.) My son is 4 and he rides his bike to school. I'll cycle next to him, but he does know all the rules and basics about defensive riding. I bicycled in and around NYC last year and it was crazy. Car drivers didn't really pay attention to bikers, but that was actually much less dangerous than I anticipated. The cyclists however were flipping mad! No rules, no courtesy, aggresive riding, running red lights, cutting off cars... Madness! Not all,of them, of course, but considerably more than you would see in, say, Amsterdam. The bike lanes is NYC were fantastic, though. NYC seems perfect for bike transportation, I never got why you don't see more cyclists. SFO with all those hills (like I said, I'm dutch, no hills here...) and cable cars seems more challenging!
