The only way an electron can work harder to make more conductivity is to move further before it scatters, but it has to move in this “forest of atoms.” How?

The wave packet of the electron diffracts through the forest; because of the periodic nature of the lattice, it can go on forever, if the lattice is perfect. Thermal motions and impurities make the lattice imperfect.
