ev cars are going to become power packs. usa ev cars are disposable at end of battery life. due to replacement cost of bad batteries. you can bet china will be coming out with a longer life power packs. /// it is amazing how ev cars are way behind the design curve. at an auto show in china, it displayed many advanced ev cars. i liked the ones with swing out seats. open door, swing out seat. sit. then swing in seat. and close door. no more hitting my head when entering the car. some of the mini ev cars had the drivers seat connected to the door. the door/seat was electric on deluxe models.
