The techs/people at my place certainly aren't bright enough to do that. I dunno if it's the techs themselves or if there are other people who drive your BMW in after you drop it off. I'm more concerned about the young people who drive our X in and out of the service bay........and they're certainly not careful enough to stare at two tiny numbers in the already tiny OBC display (remember, this is a 3-series display I'm talkin about on my X3......the numbers are smaller than my pinky's fingernail).
