I'd say your ideas are significantly more pie-in-the-sky than mine. Rare earth metals aren't going to get more common; they will only get more rare as more of them are extracted. That extraction process will become more expensive and more damaging to the environment, and as a result, electric vehicles will get more expensive.

Contemporary battery technology cannot replace ICE vehicles. We need to reduce vehicle emissions now, not wait until some undetermined future time when an alternative is finally viable. Biofuel is how we do that.

But sure, go ahead and ignore the overwhelming evidence and cling to your outdated idea of replacing combustion engine vehicles with electric vehicles.
