General rule of thumb is to practice during daily driving, you need to practice for up to 3 months before the using your left foot becomes second nature and you learn pressure modulation. The first time I tried practicing using my left foot I practically sent myself through the windshield.

For the tracks that I drive, left foot braking is very beneficial, but I guess it all depends on the track. No matter what it is a good skill to have in your bag of tricks.
