I don’t think what he is asking for is unreasonable and he doesn’t suggest that they should be the same price right now. What he is saying is the price of entry to electric is currently higher than it needs to be.
Specifically he is saying is that where cars share the same platform, you should be able to buy the basic C4 with the EV power train for a price. The point is you just can’t, you have to spend a shedload more.
There is clearly a market for electric and there is clearly a market for low spec cars, it’s not unreasonable to expect there is a market for low spec electric cars. They would lower the barrier for entry which is clearly an issue for a lot of people.
The main reason there isn’t low spec cars is because the mainstream manufacturers only need to sell a small proportion of electric to meet their emissions targets, they know they can sell everyone they make with little discount, so they load them up to make the most profit while still milking as much out of the ICE as they possibly can.
