In fact, I expect that almost every ICEV will be a PHEV in the relatively near future.
Not sure what you mean by "almost every ICEV" and "near future." Is "almost every ICEV" 95%? 90%? 80%?
Is "near future" five years from now? Ten?
Perhaps this is wishful thinking. Some are going to be disappointed when the realities and limitations of BEV's (as some are experiencing now) become more apparent. Natural gas is a practical alternative to petrol powered cars. I believe there will be multiple kinds of cars, natural gas, diesel, gasoline, electric, hybrid electric/petrol/natural gas.
In my opinion, 10 years from now, BEV's will still be niche cars and will make up less than 1% of sales.
