The changes needed to meaningfully change our trajectory of our society are massive and systemic. The entire present fleet of electric cars isn't going to have a substantial effect let alone one scientist doing so. People in many parts of the US especially can't afford to give up driving and keep cars for 10 plus years. Buying one will set you back 30k+ now and EV have only recently got so "affordable" along with infrastructure becoming slightly more prevalent. One would therefore expect those scientists making enough money to afford an EV to be more likely to choose an EV as they naturally upgraded as opposed to the ridiculous hypothesis that anyone who believed in their research ought to have them.
