Well, if you really wanna get nerdy, here goes: To find the percentage of lefties who drive stick, take the number of drivers who are lefty and drive stick, divide this by the total number of lefties who responded. For example, if 5 people vote lefty-stick and 2 vote lefty-DSG, divide 5 by 7 (=0.714). If you multipy this by 100 you'll get 71.4%. In that example, 71.4% of lefties drive manual.
