It'll be a 30-50 year process. I don't even think that's a question. Look at the phase-out of leaded gasoline, it wasn't fully banned from sale for on-road vehicles in the US until 1996. The phase-out began in 1976. And that was a lot more clear-cut "this is terrible!" to the average person. ------------------------------- Personally, I expect most countries will never fully ban or need to ban ICE-powered vehicles, just as we don't ban you from driving a Model T or horse & buggy around today. New sales will be required to meet strict efficiency and safety standards and once electric becomes a cheaper option (perhaps with taxes/subsidies to hurry that), new ICE-powered vehicles will become a specialized niche rather than mainstream. They'll probably retain various niches for a long time, but that'll be a tiny fraction compared with current use. Already on the road average ICE-powered vehicles will rapidly taper off in demand as they cycle into wearing out and winding up in the junkyard.
