As we noted a couple of weeks ago, mechanical street sweepers will once again exert their significant muscle over local car owners starting today. Of course, technically, the District won’t start handing out tickets for violations until the March 30 — but considering the current budget crisis, we wouldn’t want to be pushing the limits of anything involving the District and fines its agencies are collecting. Anyway, be sure to keep your eyes peeled for those “No Parking/Street Cleaning” signs from now on, lest your car be subject to the brutality of the new “Sweepercam” system. (Can we start the countdown to when “Sweepercam” will be self-aware yet?)
