Spain 2001 was the race when traction control, launch control and fully
automatic gearboxes were allowed back into the sport. The better versions
allow the driver to override the shifts in a variety of ways, the most
common being semi-auto upshifts and fully-auto downshifts, or fully-auto
both ways but with an upshift override for short-shifting in certain corners
or easing the engine load on acceleration at the end of the race.
