And of that incredible energy density, most it get wasted by a significantly less efficient drivetrain.

Also, EVs have the potential to basically be "100% efficient" if they happen to be charged by solar. With combustion engines you're never going to get any sort of improvement, it's just always what it is.

Not necessarily true, things like direct injection, VVT and VVL and variable compression engines and variable vane turbos and 8 + speed transmissions have increased the efficiency of gas cars. The gas engines are still wasting a lot as heat, if you have any interest in that u should look into smokey yunick and his hot vapor engines. There are improvements to be made in ice but it will still never be 100% efficient. We have far from mastered internal combustion, and I suspect we never will as hopefully EV eventually replace most combustion vehicles.

Of new gas cars though. But by changing how you charge a battery you change its effective efficiency. A gas engine can't run on anything but gasoline. (E.g., gas and diesel engines aren't compatible with the opposite liquid.)
