How fast would a piston have to move

Thanks, B.L.E. I am glad someone besides me thinks it is silly to cruse down the highway at 2/3 of the redline speed. If it is dangerous to drive 7,500 RPMs doing 5,000 working up to “dangerous”. And of course we should not lug an engine. but with my automatic it is nearly impossible to do that.
