Shifting and thinking about when to shift is not that big a task... Driver's straining both brain cells thinking about shifting ?? They should be able to know where that shifter is with out having to study the shifting pattern on the shifter knob, or even take their eyes off the road to reach the shifter.

If they've got to 'think' that hard about shifting,, they shouldn't be driving anything that doesn't have pedals on the front wheel.
