I don't think upper management knows much about computers, or programming? I sometimes wonder just why they are putting so many computers and sensors in their automobiles? I understand they need they to get their autos past emmission standards, but it's gotten rediculous? When something goes wrong with these autos you can't just plug in and find the fault. It's an art to repair, and all too frequently, the mechanic just replaces a bunch of good sensors--praying he found the lazy one; even at the dealership.(Ask a dealership mechanic--it's a running joke.) Personally, I wouldn't buy a new automobile until everyone has open access to these propriatiary automotive computer systems? I think that date is around 2018?

But then again, maybe no one cares? I know Saturn engineers tried to make a repair friendly car(you could get to failed components, but no one seemed to care?) This was before the Internet though? Times must have changed?
