If BMW says that buying one of their EVs helps save the planet then that must be true.
I was questioning whether these folks were really saving the planet. The retort to that is not “doesn’t matter because I can tell them/convince them that they are”.
Certainly buying a brand-new EV (from any company) isn't making a positive impact on the environment. But, writ large, switching from ICE to electric cars is a giant step in the right direction. So I think it's safe to call that one a wash. Most people buying a new EV would have been buying a new ICE car anyway, and it is much better to further the electrification of transportation. Even if taking public transportation--a sacrifice--would be more helpful.
