Yes , and no .When left foot braking, if your left foot is to the side most of the time, then isn’t moving your left foot across to the brake pedal just as “inefficient” as having to move your right foot?
And if your left foot is to the side until you need to cover the brake in anticipation of needing to brake, then isn’t that the same as moving your right foot to cover the brake?
If you anticipate the need to brake, and hence the need to cover the brake pedal, then surely you take your foot off the accelerator having anticipated the hazard?
I still struggle to see the benefit for normal, safe driving on the road.
There is movement- true .
But there is less confusion . Then , as I explained in earlier posts , there can be advantages in using both at once , or in smoothly transitioning from one to the other .
I often use a little acceleration during the braking phase to bring in the part throttle downshift in the approach to a bend . Normally , during braking an automatic box will take the highest gear possible ; if you manually select a lower gear during braking , without acceleration , it will result in a ‘jerk’ .
It takes practice to master , but it IS a better way .
