For starters, I specifically said NYC which is very different from NY state. I've lived here a while and the last year before a new law took effect was in 2013. Streetsblog covered the deaths of 134 pedestrians and cyclists in 2013 (out of a total of 178 killed city-wide). Of those 134 killed, the drivers were unknown in 19. "Of the remaining 115 crashes, nine motorists were known to have been charged with homicide. In five of those cases, the driver was also charged with driving under the influence of alcohol or drugs. One crash resulted from a police chase. In two cases, the driver was accused of running over the victim intentionally. Only once in 2013 was a sober driver charged with homicide for killing a pedestrian or cyclist in a crash that did not involve a personal dispute or fleeing police."

Of the 96 cases covered of a pedestrian being killed by a motorvehicle that didn't involve a DUI, a police chase, or premeditated murder, only a single one was charged with vehicular homicide. So yeah, it's been bad for a while. The most drivers used to get was a small fine and a moving violation and then go about their lives. Heck, I watched a woman get killed by a cab maybe 15 years ago and nothing happened to the driver at all.
A law finally passed in 2014 to address the legal precedent after a 9 year old walking with his dad in a cross walk with the light was run down by a cab and the drive got a small fine and a minor traffic infraction. Here are some details:

In my original post, I should have said more than a few years ago rather than in the last few years, but I can't edit it now.
