The wall street journal recently had a commentary that only 18% of Americans can drive a stick. And only about 1% of new cars are manual.
I'm not surprised, but I lean toward manual transmission myself. But only 1 of 3 of our vehicles is a manual. A manual transmission wasn't available from the limited number of diesel pickups when I bought the duallie (2005), and it doesn't really work with the hybrid engine in the Ford Fusion (2013). Our daily drive is a Toyota Tacoma (2004), which is a 5 speed manual.
I'd guess the demographics here lean a bit more toward manual. Feel free to comment ...
I learned to drive a manual transmission at about age 12. My father parked a jeep in the corn field across from the house, gave about 3 sentences of instructions, and said bring it back to the house when I got it figured out. Oh, and don't drive in the low spot over there, you'll get stuck. Then he walked away.
@RJSakowski has probably seen that field ...
