For the record, in 99% of driving scenarios, you probably don't want to press the brake and gas at the same time. For the 1%, you can do something called brake boosting. This is where on turbo cars, you brake to maintain a slower speed, at the same time you press the gas to spool up the turbo, which results in you having little to no turbo lag while racing.
You would also do this momentarily (with automatic) when starting from a stop on a steep upward incline, like certain San Francisco street intersections. Get the gas going slightly while holding the brake, then ease off to move forward without rolling back. Because the guy behind you is always too close for comfort.
Similar technique would be used for manuals as well. You'd heal-toe on a hill so you don't roll back, same with downshifting and slowing down quickly to make a turn.
