“I’m not sure the hybrid becomes useless when the battery fades.”
It’s not useless, just declining range. I knew a car dealer very well all through his career. You trade, you get slaughtered, and old batteries are like high mileage, it’s a big drop.
When more EVs are on the road, there will be companies that just build replacement batteries. If the EV companies ever really get it together you won’t own a battery, you’ll just pay a usage fee. There will be 4-5 different batteries that fit everything on the road, and you stop at a battery station, have “your” battery switched out in 10 minutes, swipe your card and drive on. The battery you left will be charged and put in another car, etc.
Let me know when an EV can be recharged in that same 10 minutes.
