Want to support that in any single way? Like an actual source?I’d wager there won’t be ANY ev cars on the road that are 30+ years old. I’m still driving a 65 Mustang with the original engine. One rebuild in it. Know a guy that has a late 60’s Shelby he uses as a daily driver and always has. Mechanical cars will always be easier to maintain over their lifespans.
There is no way for you to know that will the way in the future. EVs are only getting better.
