You haven't worked on a late model car before. You can turn systems on an off to troubleshoot them. Before, you could do this mechanically. Now, you have to use a computer. Setting the speedometer is pretty common when a tire size is changed. Setting the odometer can usually only be done once each time you replace the instrument cluster. All I know, as someone that still likes to turn their own wrenches, is that I don't want more security on the only way I can still work on my own car. If they lock me out of the diagnostics port, I won't buy the car.

It seems like a few bad apples also spoil urban golf.

Substitute "real programmers" for "Chuck Norris" and you could have a great internet joke.
