The top end model S weighs about 2300kg, so it's not really much of a difference.

That doesn't make it better. Moving around by yourself (like most drivers out there) in a 2300Km vehicle is not efficient. It's just better by comparison because at least it's an EV. But you still use a lot of (not so clean in the majority of cases) electricity to move a lot of weight just so one person gets from point A to point B.

People want one car to be the jack of all trades. Big enough for 7 people and carry a house's worth of furniture in one go while towing a boat, and travel 800Km on a charge. So it ends up being truck sized, 2500+Kg, to carry 1 person on their 5Km commute to work 99% of the time.

  • It's all relative. You could build something that weighed 100kg, so anything heavier is a waste of energy if we only look at ability to go from point A to point B.

    But it would be a death trap to drive around other 2000kg vehicles, and it wouldn't be comfortable.

    >5Km commute

    Almost no one in the US has a commute that short.

    • 99% of the people could do with a sub-compact 99% of the time as seen everywhere else in the world. Are the only 2 options you see a 100Kg dingy or a 2500Kg fat-mobile? It's like saying you can't have electric cars because how far can they go on 2 AA batteries.

      If that's a death trap around the "real" vehicles, should cyclists and pedestrians expect 90% mortality rate should they ever decide to go out on the streets? Is that normal?

      It's all relative. You just multiply that (avoidable) waste.

      Do you really need to drive a "tank" just to survive? https://news.ycombinator.com/item?id=21609767
