First, his logic was logical, not twisted. If you could drive a race car, in the real world, faster with a 1/2 inch stick, then they would incorporate that into real race cars. (no twisting going on, just common sense)
Second, the people you speak of either haven't used a wheel, or they haven't put enough effort into getting good with a wheel.
The bottom line is everyone will be faster, more consistent, and have more fun using a wheel/pedal setup. This didn't come from my rear, it comes from knowing people who were real fast with a controller (faster than a lot of guys with wheels) and all the attributes I listed were enhanced through using a wheel/pedals.
