These morons did not debunk any myths about manual transmissions - Toyota Yaris Forums

the gearing is not the issue with CVTs and ATs actually, it's the power/efficiency loss during the transfer from Engine to Tranny.
ATs use fluids with gear teeth (efficiency loss on the fluid part) and CVTs use belts with no gear teeth (efficiency loss on the belt). Only Manual trannies use direct metal-metal and with gear teeth.

to paint the picture, exaggerate the results of a biker using a mountain bike with those 2-/4-stroke scooter-like trannies (CVT), he will lose a lot of efficiency with the power he puts out from his legs due to slippage of the belt.
