I know it's a meme, but I'm going to rant for a bit.
The MT version of the air conditioner is the two knobs, one for temp and the other for fan speed. The AT is the temp setting where you pick a temp and the air blows until it's that temperature.
And the MT is far superior in every way. Most car trips, you're not in your car long enough to stabilize the temp, and if you're like me, you never bother with anything between max cool and max heat anyway.
