@rit_wht@hieywieyneue My father in law was a gearbox, I asked him, how can we make cars with a lower cruising speed without affecting efficiency. We can't, he said, we don't know how anymore
@Branche_SC its the other way around, you can make them any shape because the parts don't constrain design as much as ICE + transmission.
that's the problem, give a designer a (more or less) blank slate and they will typically do a poor job, constraints are helpful
