The rare earth metal problem is blown totally out of proportion.

Their biggest use in hybrid cars was in NiMH batteries, but they've now been replaced by lithium ion.

DC motors need some for magnets, but modern electronics make induction motors almost as competitive, and they have no magnets.

The Tesla Model S, for example, doesn't use any rare earth metals in the drivetrain.
