Gasoline gallon equivalents should die in a fire. It's an invented statistic that's meant to give you an idea of how much you'll be spending to run an EV compared to an ICE car, but there's so much slop in the numbers, and they can change over time.

Also, can we kill off hp for cars? Your EV's battery will be rated in kwh. Your motor can be rated kw. These numbers work together and is exactly what the metric system is best at.
