The Texas "rolling coal" case shows you can attempt to murder a group of cyclists and face no legal repercussions if you are in the right political climate.
That being said, these are edge cases. The sad reality is that a driver must display extreme levels of negligence or malice before the state will step in to punish them. In NYC only 1 percent of drivers who injured a pedestrian or cyclist even got a ticket. Assuming the driver is sober and doesn’t flee the scene, neither cops nor DA’s really care about prosecuting negligent drivers who injure or kill anyone.
