As the charging time for EV batteries has gone down dramatically ( currently fast charging to 80% capacity in 20-30 minutes), there is no need to have such big batteries anymore. They could be reduced in half for many use cases. In addition, the motors are often way too powerful and can be made smaller. And then if there would be further issues with cost, the size of the car could easily be reduced. It's quite ridiculous to make big SUV's which don't fit more people and load than a more traditional car. It will regulate itself, based on cost of raw materials. And hopefully governments will at least provide incentives to steer it towards smaller cars (for example more tax on big and heavy vehicles). The subsidies do not change the cost of the car for the buyer. With subsidies, it just allows the car manufacturers to charge a higher price. If the subsidies would be taken away, the car manufacturers would decrease their prices.

Ok this is the comment that made me realize you literally have no idea what you are talking about. The motors are used to capture energy while breaking, if you can't capture energy because you are maxing out the smaller motors you lose that energy. That's why the motors are the size they are, the high performance is just a benefit of that requirement. > And then if there would be further issues with cost, the size of the car could easily be reduced. This is irrelevant. > The subsidies do not change the cost of the car for the buyer. With subsidies, it just allows the car manufacturers to charge a higher price. Again this is false, that is not how pricing of goods works. You have to price your widget to sell on the market, not just to hit some hypothetical price you think it is worth. The subsidies don't let them raise prices because they are competing with other cars, not just with their own hypothetical price.

When the market is balanced you might be right, but when there if higher demand than supply, which is the case at the moment, then there is no need for the suppliers to lower the prices. They can keep the subsidies in their pocket without passing it on as they cannot sell/produce enough cars anyway.
