I learned this afternoon that one of the dealer prep steps is to replace "factory" software with the latest "end user" version of software on the car. Which begs the question -- how does the odometer get protected from hacking? What if our cars run a zillion miles on the factory software and that ODO reading gets overwritten with "50 miles" when the first round of end user software goes on the car? Who's to know? On the bright side, at least our lifetime average power consumption isn't skewed by all the drag races the factory folks are having with our cars right now.
