I use 2 pedal operation during slow speed negotiations and find having 'gravity pull' available at all times is a needed feature. Hold the accel while you are waiting with the brake ON until the coast is clear. Then let off the brake and LAUNCH. Do not mind the nanny chimes!!

My bad. At a certain steepness touching the brake will KILL accel, forcing you to start over again with the accel pedal. I run into this driving up (steep) trailer ramps. The proper way to drive up trailer ramps is *never* hit the brake until all 4 wheels are up on deck. If you chicken out and hit the brake the car coasts back and you have to start all over. So this is what the OP has on his driveway, just not as steep. He should try just not using the brake at all.
My MS has creep ON (when did that happen?).
