A shopping center nearby uses flock to "ticket" and fine employees that park in residential streets (which creates bad relations with neighbors) instead of the designated remote parking. I guess part of the lease/employment agreement states the proper directions or fine will be incurred. An employee drives around in a golf cart with an app/website/scanner/not sure. I know they use Flock though because it's been mentioned in community zoning meetings w/ regards to their expansion efforts.

Kind of interesting you can pay for a private service which will uncloak license plates. I wonder how much it is as I'd love to uncloak neighborhood speeders too.
