Current battery tech just isn't that good. A Tesla battery pack weighs 900 pounds and only holds the energy of 3 gallons of gas. They are also a hell of a lot more expensive and wear faster than a gas tank.

Carbon hydrogen bonds are one of the best ways to store energy that we have.

A Tesla battery pack is good for about 300 miles. If that's equivalent to 3 gallons of gas, that's saying that Teslas would get 100mpg.

I can believe 40-45 mpg, but 100 requires some evidence.

They are rated for 134 combined MPGe. That is not that crazy for an EV, the ford Mach E gets 93:

Electric drivetrains are really efficient, which is why EV's are practical at all.
