Maybe they will increase their prices for now. But in the long-term and even in the medium-term, EV manufacturers will have to find a way to make and sell their vehicles for less. Otherwise EVs will remain a niche product for the wealthy and/or a lot of EV manufacturers eventually will go out of business. I know that batteries cost a lot to make, but I hope that if supply bottlenecks are resolved and new battery materials and battery-making techniques are adopted, battery prices can start to come down again. Aside from batteries, other aspects of an EV should be no more expensive to make, or even cheaper for some elements of the vehicle. Currently, manufacturers are targeting the upper end of the market with a lot of extra technology and features, and it is great to have to those vehicles, but not all EVs have to be high end.
