Pointing out you're equivocating lifecycle emissions with tailpipe in response to an assertion about energy is just pointing out you haven't reached the goalposts even after moving them.

A tesla 3 (top selling ev) uses about 170Wh/km. From a very low efficiency coal plant including transmission and charging losses (you don't get to double count discharge loss) this would be about 0.6kWh (thermal) or about 170g of CO2e. From a natgas plant it is 90g.

A CX-5 (top selling car) is a bit lighter and gets about 8L/100km. This is about 1 kWh or 2kWh including drilling/refining or roughly 250g of CO2e.

You could correctly argue that teslas are replacing smaller, lighter cars with bigger heavier ones, and that the smaller ones they displace have marginally lower CO2 emissions in spite of using double the energy because oil is lower CO2 than coal, but that's about as far as you can push it. If that was your argument then the solution is LEVs, transit, and bike lanes which is what the environmentalists you're straw manning want instead of most cars.
