People in New York City could be paid a proportion of parking fines, by reporting illegally parked cars.

Route-Fifty.com reports the bill, sponsored by City Council members Stephen Levin and Corey D Johnson, would give parking whistleblowers 25% of any fines resulting from reports of cars that obstruct bike or bus lanes, pavements, crossings or fire hydrants located near schools. Not every car would be subject to the policy—only those parked illegally within a “radial distance” of 1,320 feet of a school building, entrance or exit.

Route-Fifty adds that Levin said the bill was not designed to increase revenue for the city, just to make streets safer for pedestrians and cyclists.
