Sounds like they are gearing up to go even further than phone calls:

> In a statement, an NYPD spokesperson expressed concerns that the proposed law could lead to violent conflicts between drivers and civilians reporting illegally parked cars

There's precedent for this, or rather for people figuring out a way around it. A NYC law that paid rewards to those to report idling vehicles. A few people make non-trivial sums doing this. They act like tourists or like they're lost in a phone conversation so they can hang out around the vehicle and record the violation. They have to record the truck idling for a few minutes to collect the money, so without a disguise they risk being beat up.
