Obviously we are not comparing about the weight of an EV compared to an apple or vehicle that doesn't require a battery. We are talking about extreme measures taken to make the car lighter so it can improve range. Replacing cheaper steel with more expensive aluminum, reducing even surface area of plastics, reducing wires. Truly amazing steps were taken to reduce weight.

> No it doesn't! It has horrible energy density per volume,

volume? Seriously? "The energy in 2.2 pounds (1 kilogram) of hydrogen gas is about the same as the energy in 1 gallon (6.2 pounds, 2.8 kilograms) of gasoline." https://afdc.energy.gov/fuels/hydrogen_basics.html

You're comparing mass to volume in that last paragraph there. Based on a quick google search, that 1 kilogram of hydrogen is going to take up 3.4 gallons as a cryogenic liquid—so even more as a compressed gas.

Well, yeah that was my original intention. Teslas get comparable range to ICE vehicles while using less than 3 gallons of gas. That comparison to ICE vehicles demonstrates the efficiency of electric vehicles.
