No, I am not worried that it will go down in value.
But I am worried that it will go up in value, which would mean that there aren't enough EVs made and we keep lining the pockets of oil dictators.
I like the bigger picture view here.
It's an interesting dilemma. Selfishly I'd like my car to not depreciate, so I can plan ahead to replace it while someone not in my situation buys it off me at cost. Makes me feel good and smug.
But... My selfishness doesn't help the majority. The majority don't buy new cars, so it's a cheaper second hand market that will really drive EV take-up.
So I also won't worry whatever happens.
