I thought going directly to BEV was a good plan, but then someone on this site pointed out that if civilization needs to go to BEVs, and there is X supply of battery materials, should we use those in 100kwhr packs for full BEVs, or in 20 kwhr battery packs for PHEVs that will deliver 80-90% of trips electrified?

So you effectively electrify 5x the number of cars...

But, that opportunity has passed, at least we are moving towards electrification.
