Yes electrons flow through the path of least resistance. But what this guy is missing is, its not just the material type that dictates resistance. If we were to believe this guy, a single run of 20ga copper wire would display less resistance than would a 20 ton piece of steel, simply because the wire is copper.Trust me, your car's steel frame will show less resistance than will any realistic sized copper wire. But again if your car doesn't have a frame, yes check it out with a DMM, or just go with a ground cable back to the batt if you are worried. But dont fool yourself into thinking that is always the best method.Glad to help.</blockquote>
