Profit centre?

Still with the left arm in a sling, I was taking a cab to work. I saw a cop wearing a skimpy Sam Browne waving a motorcyclist over. The busy, haggling collection of bad-haired riders said clearly, Anti-Helmet-less Riding Drive. Then, a chap with a untethered pudding basin atop a motorcycle blew by the cops without meriting even a second glance... A few kilometers down, I spotted three more cop posses surrounded by a bunch of riders. Is this a safety drive, or have the cops fallen behind their revenue targets again? Remember, the financial year ends in March.
