i think it would be a better idea to strictly implement safety regulations. honestly, ang daming mga kotse na mawawala sa kalye if they start apprehending run-down vehicles (smoke belchers, tagilid na bus, vehicles with no side mirrors, etc). parang law of supply and demand, yung mga gusto lang talaga or kailangan lang talaga ang gagamit ng kotse because of the maintenance costs. i think the increase in vehicles due to the removal of coding will be offset by the decrease of run-down vehicles on the road. less accidents also (which, incidentally, are another cause of traffic jams)
