Umm a manual transmission has a stick and clutch, as opposed to an automatic. So I'd say somebody who who learns an automatic, or a video game (Gran Turismo), can drive the automatic and maybe a go-cart. A clutch driver could certainly drive an automatic (I find the mind-numbingly boring myself), a golf-cart, and probably a forklift and maybe a semi (a lorry).
