The head of the state Association of Chiefs of Police is calling on Gov. Cuomo to expand ride-sharing services like Uber and Lyft to upstate to curb drunk driving. In a letter to Cuomo, Cheektowaga Police Chief David Zack wrote that upstate accounts for 51% of all licensed drivers in New York, but 65% of alcohol- and drug-impaired arrests and 59% of all fatal and personal injury crashes.The percentages are significantly lower in New York City, which offers an array of ridesharing and mass transit options that upstate does not, Zack wrote.
