While the MTA regulates the taxi industry, the state Public Utilities Commission has claimed jurisdiction over the new ride services, which typically contract with people to use their personal cars to carry passengers who hail them with a smart-phone app. The new companies, unlike taxi operators, have lesser insurance requirements, no restrictions on the number of vehicles they put on the streets, no clean-air standards and less-stringent background checks. Among biggest impacts of the ride services has been the drop in taxi rides taken by people in ramp taxis, which carry people in wheelchairs. Director Malcolm Heinicke wants to make it mandatory for taxis to have e-hailing apps, and taxi drivers said they want the city to keep ride services and limousines out of transit-only lanes and taxi stands.
