..or just do not use variable names smaller than 3 characters if they do not mean anything, period. There is no difference in coding time and no good reason whatsoever.

I generally agree, but I think ii, jj, kk are fine for those iterator ints in loops, or the throwaway var in a list comprehension in Python.

The only other situation single-letter variable names make any sense is if you have a short function that implements a mathematical formula, like distance or something.
