Scarce metal resources?

ROFL.

The only metal the slightest bit scarce in cars is a small amount of
platinum in the catalytic converter. By no stretch of the imagination could
(say) Iron or Aluminium be considered scarce; we have massive proven
resources of these and they are extremely common.

The only scarce part is the capacity to build more mines and smelters,
which may jog the markets for a while. Aluminium is also pretty energy-
intensive, so they will need that energy from somewhere.

If the best argument you come up with is that we are running out of metal to
build cars, you have no argument. We are not.

Rubber is a bigger obstacle to building more cars.
