Sorry to disappoint you sir but I'm afraid you could not be more wrong.As battery longivity improves petrol engines will be phased out , in the UK there is a government agenda to phase out petrol and diesel engine cars within about 20 years, it will certainly not stop there will it.
That govt. agenda is a load of tosh and will have to be rescinded, we don't, and won't, have the generating capacity to power ~ 30m cars, even for commuting, never mind longer journeys.
We're buying most of France's spare power as it is, and if La Nina gives us a cold winter, we're likely to have brown/blackouts.
It's the legacy of throwing all our money at the scam that is "climate change". We could actually afford something worthwhile in terms of the environment, by building half-a-dozen cheap, out-of-town, natural gas generators, to keep petrol-fuelled cars out of cities.
