Anyway, given that in real-life, you have only two (!) feet and 3 pedals (!) - assuming manual transmission with clutch of course - and by default the left one is assigned for the clutch, it's clear that one can't effectively access the accelerator AND the breaks at the same time.
Breaking while accelerating at the same time is pretty pointless... it won't make you accelerate nor break better..
This is patently false.
Full disclosure: I work for Microsoft, and used to be a member of their Racing Games studio. That does not change the fact that the statements above are incorrect, however.
Using the brakes and gas simultaneously isn't just possible -- it's a requirement for track work in a car with a manual transmission. When downshifting under braking, the engine needs to be sped up from the rate at which it was turning in the higher gear to the rate that it will be turning in the lower gear. If you just drop the transmission into gear and let out the clutch, the rear wheels will lose traction since the engine speed doesn't match the road speed. In order to avoid this, you have to use a technique called "heel-and-toe downshifting" -- braking with the ball of your right foot while simultaneously blipping the throttle with the heel of the same foot.
But that's not interesting for GT4's purposes, because shifting isn't modeled to that level of detail. What
is interesting for GT4 is left foot braking, or using your left foot to brake while still using your right foot to feed in throttle. There are several advantages to this approach. On FWD cars, this technique causes the rear wheels to be braked more aggressively than the fronts, allowing the car to rotate better, much as it would if you pulled the handbrake. Conversely, on RWD cars, left foot braking causes the front wheels to be braked more aggressively than the rears, stabilizing the car and reducing its tendency to get tail-happy under braking. Last but not least, left foot braking allows quicker transitions between braking and gas since your feet are already on the appropriate pedals, instead of moving back and forth between them.
Don't believe me?
Ask Michael Schumacher.
Incidentally, "braking" is done to slow a car before corners. "Breaking" can also slow a car, but is nonetheless something that racing drivers try to avoid.
