I was learning to drive in gas-powered car in netherlands. In the middle of the lessons, we switched electric car, hyundai iconiq to be precise. I think sales are higher not because electric cars are cleaner than gas-powered cars, but I think electric cars have way much better user experience inside and out of the car. It just feels more modern and I think people will switch to electric just because of that.
I really think gas-powered cars will become niche.
