Manual transmissions are a giant leap backward in technology, sort of like yanking all the computerized fuel injection stuff off an engine and installing a carburetor. (Some folks do that, too!) How about installing a crank instead of a starter? Clincher rims, and high-pressure tires, maybe?
Here's a suggestion- - - -a stick shift is something for a driver to play with, so why not install an automatic transmission, and cut the pockets out of your pants? You've got a toy that's more pleasing than a stick shift, and a better-performing vehicle, too!
My students love it when I explain it that way!
