I recently bought a nice new Model 3, for environmental and road-safety reasons, but I still own a perfectly-functioning 1998 Honda CR-V that I've driven for the last 21 years. I didn't trade in the CR-V at the time of the Model 3 purchase because I would only have got minimal cash for it, and I thought it might be better to scrap it instead, rather than it being sold on to someone else who will run it for another 10 years, spewing out CO2, particulates, etc. However, I'm not even sure how easy it is to ensure that a car does get scrapped, if you sell it to an "auto recycling" place - I guess it would be in their better financial interest to sell functional cars on, rather than actually scrapping them. But maybe I shouldn't feel too bad about the next person still driving my old car around for years, because presumably it would displace the even worse car he/she was driving. And eventually, some cars will drop off the bottom of the ladder and get scrapped. What are people's thoughts on these auto life-cycle questions?
