Learner drivers need all the help they can get.
I still remember when driving a manual car for the first time, that my feet had a hard time working out where the pedals were…you tend to discover that you are braking rather than operating the clutch only by the dynamics of the vehicle as it responds…which is much too late for safety.
Today’s invention is a set of attachable sensors, one per pedal. When one’s foot hovers over say the brake, a different sound is emitted than from the accelerator. The strength of each sound could be made proportional to the central positioning of the foot. I’d also suggest making the noises resemble the normal sound of braking or accelerating (ie dropping in pitch or rising).
This allows an early-stage learner to stop trying to look at his feet and anticipate the next action required.
