Something super simple and revealing is try pressing on the brakes with your left foot.

That's because after you've learned to drive, everything the feet do is muscle memory. You don't consciously adjust the pressure (you just believe you do..), so switching around the pedals will need re-learning. And indeed it's common among rally cross drivers to learn to use the left foot with the brake pedal as well.

I do this once or twice a year in a borrowed/hired auto car. Usually about 10 minutes into the drive when I've got used to it, and started to drive more naturally. Approach junction, throttle back, stamp full uncoordinate force of left foot on to 'clutch' pedal, send passengers through the windscreen.

If you usually drive a manual transmission you might have a bad time if you try to brake with your left foot

Yeah it’s a big contrast, I guess that’s why I mentioned it. I forgot it would be easier to learn with an automatic, or at least the difference wouldn’t be so obvious with it.

A few of my relatives who grew up on a farm drives that way (right for gas, left for brakes)

Useful for controlling a car at speed through tight turns though

IMO heel-and-toe is harder than left foot braking.
