Just pull the parking brake and accelerate until you feel the car slightly raising and then drop the parking brake.
Eventually you get a feeling for it and drop the parking brake before it’s “fighting” the accelerator.
This might sound trivial to some, but I know several people that never use the parking brake in these situations and instead do a manic race with their feet and the car drops a couple meters back and they over accelerate to compensate.
It drives (pun intended) me nuts, but they don’t listen to reason. And the worst of all, is that they got their license in a hilly town and say they weren’t taught that. While I learned in a flatter place and was taught this.
