Oilseeds like rape and sunflower are not grown for ethanol, you need starchy crops like wheat. Oilseeds are grown for food, and for biodiesel, although the value of sunflower oil for food is much higher than mineral oil. As for drag racers using "alcohol", it's more methanol not ethanol and there is basically no point trying to draw comparisons between a drag machine and a road engine.
