Cujet makes excellent points. Old ICE vehicles can still work; perhaps marginally less efficiently but it's not uncommon to see 50 year old ICE vehicles (which would be from the 1970s) on the roads.
Think about an EV in terms of your cell phone or laptop. After a few years, the technology becomes so obsolete that it's no longer supported, battery designs change and are not compatible, batteries die and are no longer cost effective to replace, etc. We are going to see a massive dumping of EVs prematurely, probably 10 year life spans.
Heck, look at the original Prius and Leafs. I don't think those lasted long on the used market. The 1st and 2nd Gen Prius (2000-2009 era) and the 2010 Leafs are undesirable. And don't claim "infancy technology." The battery powered car technology has been around for 100 years. It's just not successful nor desirable by most people. So what this means is that while ICE cars can be made to last, and even very desirable, for 5+ decades, not so with EVs. You're realistically looking at a 10-20 year lifespan. Great for car companies. Terrible for consumers and the environment.
