Pretty sure the left pedal is the clutch, not the brake. And the steering wheel doesn't accellerate.
A change in direction is a change in velocity
It changes the direction of the velocity vector, but not the magnitude.
Which is an example of acceleration.
Meanwhile me noob in physics:-
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
