I would consider BEV for the "shopping trolly" but not for anything else.
Makes sense to me. Of course, if one wants to do one's bit to save the planet it makes much more sense to simply keep the car(s) one has rather than changing them every few years. BEVs make sense from an economic viewpoint if one has access to home charging from solar panels, but otherwise they are a heck of an expensive way to save a few quid.
To my mind, the 'must have something new' consumerist mindset is far more damaging at an individual level than burning a few extra gallons of gasoline every year.
