Hehehehe. Got a good chuckle out of that. My comparison is/was Toyota. A truly phenomenal place to be an engineer. The worked very hard to NOT hire any democrats, er ... I mean dumbasses. The only way that code got through is to have been reviewed and agreed upon up the chain. So ... either the whole chain realized something we may not realize, or they possibly could have all been a bit dim.

Data storage. I'm not saying I'm right about it, don't get me wrong. I could be wrong. I'm wrong every damn day ... The Warden makes that clear. However, I think it was a vehicle I own(ed) that I was reading about this very thing in the owner's manual. And the owner's manual had a blurb in there indicating that at some certain mileage (seems like it was in the 4,000 miles range), the Avg Mpg data would begin to overwrite, just because the capacity of the computer that was providing that data was small.
Both auto manufacturers I designed for liked to make EVERY SINGLE part of the vehicle be as inexpensive as possible. They would make a change to save $0.02. Toyota would save $0.02 a vehicle after some "decision matrix" process indicated the impact to the customer was either none or unsubstantial. Toyota rejected many change ideas under my responsibility because there was even the slightest potential customers may find some aspect of the new part / shape / process / whatever to be unfavorable. Hyundai-Kia would make a change for $0.02 at any time for any reason customer be damned. Hyundai-Kia would make anti-rattle material out of cow manure if they thought they could save $0.02 a vehicle. $0.02 a vehicle x 350,000 vehicles a year is = $7,000 a year savings. They'd do it all day, every day, send workers in on Sunday to do it.
So I would imagine that goes for the hardware that effects data capacity of this fuel mileage thing in the Mirage.
