The one prediction I've seen (not here) that I agree with is that the Model Y will be the highest selling vehicle in the world in 2023. But I don't disagree with you about BEVs. I think companies will focus on hybrids as much as BEVs.

A 50K€ base model car as top 1 is a pipe dream. It'll happen when people can't buy cars anymore and all remains is the rich and robotaxis.
