In NY State, it is a felony to leave the scene of any accident where there is an injury. With somebodies dash video, the police can arrest that driver. The police often don’t give a **** when it’s a cyclist and often will not follow thru when they are legally required to, see it all the time. There was a cyclist killed a few years ago on a local service road. Security cams know the car was an older model, silver Dodge Caravan. You would think they would investigate and maybe find that vehicle with some potential body damage, instead the local police did no follow up, that killing went unsolved.
