  Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

  A change in direction is a change in velocity

    It changes the direction of the velocity vector, but not the magnitude.

  Left pedal looks more like a dead pedal to me.

  And as others have said, change in direction is still acceleration. That’s part of Newton’s (apocryphal?) apple story — he witnessed an apple falling, and wondered why the moon doesn’t also fall. His amazing insight is that it does fall (accelerate), it’s just that it falls in such a way that it orbits, rather than hits, the Earth (for timescales relevant to a human).

    Agree 100% on the dead petal. Every manual transmission ive owned has the clutch and a footrest, so it actually appears to be 4 pedals if you dont know what youre looking at
