I am referring to one of the answers to this old question. I can't add comment to it because I don't have enough reputation. So here I rephrase the question: does resistance increase with length because of more scattering? Suppose that while doubling the wire length I also double the voltage across the wire. Then $R$ is doubled and so is $V$ hence you would get the same current. But obviously those charge carriers would experience more scattering.
That resistance increase with length because of more scattering does not seem to be right can also be seen from the statistical point of view. Keeping everything the same you should not expect the mean waiting time (for the next collision) to change when you lengthen the ``trip''.
Any objection to my opinion?
