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).
Do you still start in 1st? Do you skip gears?
