The looming copper shortage does not just coming for EV's. ICE vehicles use a substantial amount of copper (and other metals). "Starters, generators, and alternators contain an average of 2.8, 2.6, and 1.5 pounds of copper, respectively. Alternators also contain 3 to 4 pounds of aluminum. Most of the remaining metal is iron. About one-half of the starters have a solenoid that contains 0.5 pounds of copper." [0]. So that's at least 4.3 lbs (1.95 kg) of copper per ICE vehicle, not including uses in electronics etc.
