haha this thread is funny!
i have to agree to some of the above mentioned ocd habbits...
ok so mine are:
sunvisors and middle visor thingy have to always be down... if your a passenger deal with it, you dont need to move it back up as you dont need to look out the window!
climate control shows the same temp on both sides... only exception is when the other half is in the car and she is too warm while im still cold so i turn it down her side or she will start to break out in heat spots
i have seat belt pads on my car, these have to be moved all the way to the top so that the belt fully retracts... annoys me when passengers just leave them half way down the belt and then the metal part of the belt hits the b pillar
the passenger seat must stay level with the drivers one.
nothing is allowed to stay on the carpets after i get out... this includes bottles!
No one is allowed to touch the glass! i dont care if its steamed up and you want to draw a face... i will break your fingers!
all the headrests have to be as low as they go on the seats.
thats all i can think of right now
