2255kg is the maximum load, and 1700kg is not at all an ordinary car weight; hatchbacks are often closer to 650 and my sedan is barely over 1000.
You could argue that those aren’t luxury vehicles, but downmarket EVs need to be heavy too, because batteries do not match the energy density of petrol.
Myself, I’m replacing nearly every car trip with biking where feasible (young kids make that challenging, admittedly, but the car doesn’t see a ton of use these days).
