The question is not quite as deep as wondering about the meaning of life, but I am still wondering.

I figure it's not for mechanical reasons (more flexibility or such) becasue there are cases where the part to be grounded does'nt move relative to the grounding point.
But then there are a lot of grounds done through wires in our cars.

So . . . why is the ground strap between the trany and the trunk floor a strap ? and why is the equivalent a strap in most cars I've seen ?

Thanks
