I don't get this "everyone must be EV only" mentality - utility companies in the US are already complaining about the strain EV cars put on the grid, and again that's in the US, there are huge swathes of the world that need cars and trucks, but do not necessarily have any grid at all, not even an unreliable one. If every manufacturer goes EV only, then you'll just get new manufacturers popping up to serve the fairly giant "EV is not viable" option.
