My sidekick has the clutch switch bypass so I can start it in gear to climb out of a sticky situation.

But you don't have to use them all 3 at the same time, no?
Just release the clutch gently until you feel it starts to grip. That alone will prevent the car from rolling back, or at least make it happen much slower.
Then you take the right foot off the brake and hit the accelerator.
Since the clutch is already set sharp you only have to release it another tiny bit to make it grip more. Easy as what.

We don't have a lot of hills here but we do have waterways with lots of traffic and bridges that open to let the boats through while the cars wait on the slopes toward the bridge.
The hill brake test is taken very seriously here.

I used to do first timer motorbike rider lessons.
Before we let people roll off with a bike we set the bike against a raised sidewalk block and made them work the (hand controlled) clutch, gas and brake to gently power the wheel onto the edge and off again.
With nothing else to worry about most people mastered that within a few minutes.
Once it got in their system they automatically did it right when on the roll.
