This was pretty telling from that streetsblog site...
Of nine fatal crashes reported by Streetsblog and other outlets, no motorists were known to have been charged for causing a death. The truck driver who struck Lillian Cruz was cited for failure to exercise due care. Historically, nearly half of motorists who kill a New York City pedestrian or cyclist do not receive so much as a citation for careless driving.
This pretty much supports the general feeling in A&S regarding the "teflon nature" of motorists involved in traffic deaths.
The typical response from the occasional apologists here is that the situation can be resolved by civil suits... which tend to only occur when a family or loved one is not in too much shock to pursue such a suit.
