look at the incandescent light bulb. We didn't need to legislate away the traditional bulb. LED bulbs eventually came to market and were a superior product. We spent how many millions on give-away compact fluorescent bulbs that people just threw away.
let the market dictate. If EV vehicles are superior... the market will move.
Tesla is months away from full self driving in all its vehicles. That is a superior product compared to an ICE. The market will move.
