Nor is the driver called upon to perform any awkward evolutions or sideway movements with the single pedal. He — or she — merely presses it down with the foot in the usual way, or raises it with the toe when reversing, and all the operations of driving take place automatically one after the other with no more attention than the regulation of the pressure of the foot. To realize what this means, imagine yourself having to start your car half way up a steep hill, with another car close behind.
