In a nut shell:
Understeer = Car not turning enough
Oversteer = Car turning too much

Oversteer is sometimes a good thing, such as sliding around a corner (i.e. WRC racing on SpeedVision). This is when you want the arse end to come around quickly on a tight turn. I personally cannot think of a situation that understeer is welcome. Usually I curse my worn and all too narrow front tires. Does anyone know when understeer is a good thing???
