Well, I don't think protectionism helps. Whoever wants to ramps up EV adoption and make an affordable mass market car, it helps.
But it is stupid to give a quota to each manufacturer. It is obvious the early pioneers do all the hard work, do the ground work, lay the roads, make EVs attractive, show the others how it should be done through trial and errors. And then what happens? By the time the first movers barely settle down, the rug is pulled underneath and the Johnny come latelys enjoy the fruits.
