Exactly. Main problem is battery energy density. Cars can drive about 20 kilometers on 1 liter of gasoline. In comparison, Tesla's 4680 cells are at about 272-296 Wh/kg and CATL's Kirin Battery at about 255 Wh/kg. A bit efficient EV often uses 200 Wh/km, so for 1 kg of battery the electric vehicle can only reach 1-2 km. An order of magnitude difference. Theoretically, batteries could go to 1000 Wh/kg some day, which would mean about 5 km per 1 kg of battery assuming all else remains equal.

The Model 3 manages < 140 Wh/km, and many seem to be under 150/160/170.
I'm at 115,000 km, at 133 Wh/km since the last (inadvertent) trip reset. The previous one (for the life of the vehicle) was at a similar number.
This is on a 2022 Long Range Model 3.
That’s still around 2 km per kg of batteries.
Oranges to apples so long as electron mass is fixed and reserve currencies fluctuate.
