Every time I take my D90 to get inspected (here in NC you have to do it annually) it is funny to watch the guys figure out the quirks of the truck from the moment they get in.
Some take a minute or two to figure out how to even open the door and then finding the ignition switch and then having to turn it backwards. I know I should not be so mean but it was so hot outside I left the truck in the bay and went in the air conditioning!
The next is figuring out how to honk the horn and turn the headlights on. I know childish but still rather funny. I still hold my breath on the emissions portion of the test!
