It’s simple. Build an EV with a longer range, faster charging, lower cost, and lower cost of ownership than ICE. All without subsidies, taxes, and fines. They would naturally become the standard. Until I will take the best vehicle for my needs.
There should be more electric-vehicle racing. IC-powered racing led to a great many automotive improvements, and I’ll bet the same would happen for EVs. There’s a lot of ingenuity applied by people looking to win a race.
