I don't find my wife's miata easier to heel-toe because the non-tilting wheel just about rides on my thigh (actually quad). The footwell is just super cramped in that thing.
Marius, put the ball of your foot on the right half of the brake pedal. Now ROLL your ankle to the right and stab the gas with the side of your foot. Heel&Toe actually is more like Toe&Side!
