Yes, riding a bike in New York City traffic is generally dangerous. I fixed it by moving out of New York City.
Except for the time on a quiet suburban street when my drivetrain inexplicably locked up (never figured out what actually happened) and threw me over the handlebars, or the time when there wasn't much traffic around but there was some slippery garbage truck sludge exudate that I didn't see, which I wiped out on. My helmet saved me in both of those situations too.
It turns out that shit happens in general no matter who or where you are, and that dressing for safety actually does keep you safe. An inflated sense of ability to protect oneself does not amount to protection in the event of a crash.
It is still oddly too much and each time on head. Most bike falls don't end up hitting head either. You seem to be crashing more often then ordinary and the amount of times you hit the head is higher then ordinary.
And yes I use bike fairly often. I know multiple people who use bike fairly often. The only people actually hitting protective gear that often are the ones doing mountain biking. (Which seems to be genuinly dangerous even with the gear.)
