> I have found, in NYC at least, bicyclists are a much greater hazard to pedestrians than cars.
I'm sure it feels like that sometimes, and I have no doubt that in NYC that you have witnessed some bad bike behavior, but even in NYC cars are the greater threat to pedestrians by a long, long way. Here are some statistics:
Just so you don't have to read through all the links, in the three years 2014+2015+2016, there were 3 pedestrian fatalities and 932 injuries in all accidents between a pedestrian and a bicyclist. In the same time frame, there were 32,217 injuries and 421 fatalities in all accidents between a pedestrian and a car.
Between 2002 and 2016, there have been 10 pedestrians who died from a bicycle collision, and 2,345 who died from a car collision. The rate of death from bikes vs cars is 0.42%.

Something to keep in mind is that the main reason bikers are behaving badly is defensive biking turned aggressive. It's when they're terrified of cars and don't have a safe space of their own that they act stupid. If we design better biking spaces that are separate from both the driving and the walking spaces, both behavior and safety on the whole will improve. Cities across the US, including NYC, are studying this and have been proving it true for years.
> It was enough to make me wish I had a steel pipe to stick in their front wheel and laugh in schadenfreude as they get carted off to the hospital.
I hope you never act on that wish, it wouldn't play out well for any party involved. (And, incidentally, it's not schadenfreude if you cause it to happen.)
I know that peds, bikers, and drivers at times are all frustrated and scared of the others. Take pity on the minority of assholes, rather than get angry. If we understand they're just scared and acting out, then we can ignore the bad behavior and focus on improving the situation as a whole.
