Re: Maybe 1 in 1000
"Even France and the UK plan to ban new cars by 2040 (which is rather less than your "30 years", but is distant enough that it could easily slip)."
I expect that many of those bans will be pushed some more years out until it's mostly unnecessary to implement them. There will be some that need liquid fueled cars/trucks for towing and other heavy work. The massive additional energy density of petrol/diesel over batteries will still be relevant for years in certain applications.
