Maybe EVs are not a comprehensive climate solution??
”The researchers found that people who purchase EVs tend to be wealthier than average”
In other words: OP is barking up the wrong tree as the EVs have little to no correlation with the non-EV-related carbon footprint of the EV owners.
Unless, of course, if OP is implying that EVs are too hard to acquire for the less wealthy consumers, though I somehow doubt that.
Actually, that is the case. New EVs tend to be pretty expensive and not very affordable for the average person. The second hand EV market is just getting started. Small, affordable EVs are beginning to emerge but it will be a few years until they make an impact. So right now the average EV buyer will definitely be more wealthy than the average ICE car buyer.
