Europe had already put a ban on diesel a few years ago and it was approaching fast.
I did see this over the summer. https://www.forbes.com/sites/neilwinton ... b0beba40b8
I personally think it is going to be tough to ban gas cars in this country. It is pretty ingrained in the US DNA. Plus, people drive ratty cars until the wheels fall off because they can't afford new cars or trucks. Teenagers, minimum wage workers, low income couples, etc. can't drop $20,000 or more on a new, base Versa when their rent is $1,000+/month. The Gov't would have to change the gas subsidy over to electric car subsidy in order for this to be attractive to low/middle income people or offer some incentive like the old Cash for Clunkers from the Obama era.
Then there is also the question of where are all the minerals going to come from for all of those batteries for all of those cars? Charging stations? Length of time at the charging stations charging? I shudder to think of what a Thanksgiving travel weekend would look like with all electric cars.
