I agree that it is innovative but like you I like things I can fix. I recently was watching where farmers are getting raped on diagnostics on the new tractors by John Deer and others. seems that it may cost 2000 bucks just to have your tractor trailered to the dealer and have a scan run. They are having to hack the OBD systems to save money especially for the little items like seat sensors and little gotcha items like that. Technology can be great if,,, reliability is greater.
