I can see etests disappearing in the next 4 years they are becoming redundant. Most cars from 2006 are going 7 years before it's first etest. And now with the telematics built into most new cars I am sure the goverment will just find away to get that info and send you a letter tell you to get your sh!t fixed then give you 30 days and shut your car down till it is fixed. Big brother is awesome...
