There's clearly several hidden, secret computers in the '14 Silverado. They rule seamlessly, everything from the door locks (?!) to the lights to the transmission and the variable valves, and--of course-- a fascinating digital dashboard display which tells me my current mpg, my mpg the last 50 to 400 miles, and my best ever mpg (30.5) plus other stuff like current tire pressure, how much life is left in my oil, etc. Sensors for everything! It gets mesmerizing, has me wondering how I will cope when it all crashes.
