True, but the overall carbon reduction in owning an EV over its lifetime is still leagues lower; "Production-weighted average carbon footprints are 183 g CO2e/mi for BEVs; 351 g CO2e/mi for PHEVs; 445 g CO2e/mi for HEVs; and 521 g CO2e/mi for ICEVs." from [0] which does take into account the carbon-emitting percentage of the electrical grid.
Also, see Figure 4[1] in the study which states "Results demonstrate that, even under unfavorable conditions, BEVs still have a 30% lower life cycle carbon footprint."

Emissions displacement is healthier for where humans actually live, but they do also reduce emissions over their lifetime. you and others can work on improving that further at the other parts of the stack
Thanks for the tip on what to work on. You too can work on other parts of the stack. And you can even improve the "vehicle" end of the stack, to which it sounds like you confine your actions, by moving around less, and when moving around, not hauling one or two tons of "car" with you. This can be accomplished by, for example, moving close to work (or only working close to home), living only in areas with good public transit, and/or bicycling everywhere -- all of which I did for 30 years, so I know it's possible. (edit: saved a bunch of money too)
Solar panels are now vastly cheaper and more effective than they were even a few years ago. Replacing the whole US grid won't happen overnight, but once the government is actually expending effort to move in that direction, rather than clawing in the other direction by its fingernails, it will move fairly quickly.
