I usually don't post but, let me give a slightly different perspective.
Time and time again I see vehicles that have expired inspection stickers with a rejection sticker on old heaps of junk which is marginally road or emissions legal. The owners of said vehicles avoid repairs and fines (summonses) by continually taking their junk down to the state inspection centers, where they fail and give them a piece of paper saying "repair and reinspect within 45 days of "X" date". By forcing these folks to go to a private facility the state for all intents and purposes is saying fix it or park it.
