All I was trying to do is add some support to the claim that battery density does matter in cars (contrary to ancestor assertion). Less weight = less strain on brakes and tires = less nasties in the air and our lungs.
Standard Range Model 3: 1617
Long Range RWD Model 3: 1779
Long Range AWD Model 3: 1900
2022 Toyota Camry XLE: 1630
2021 Audi A6: 1970My car is at 150000 miles and it's still on the original set of brakepads. Some EVs actually have a problem with that, their brakes are used so infrequently that rotors start to rust. So automakers added firmware that periodically applies frictional brakes.
As cost of the batteries comes down, these things will only become more popular.

Not all data is out yet but the idea that electric trucks can drive useful range without anything but chips is complete nonsense.
The gigantic of track transports are blow 300 miles and a Tesla Semi can handle that under full load and difficult circumstances.

Weight is very very valuable on both passenger cars and commercial trucks. Hauling those extra 300-500kg vs a comparable size sedan comes at a steep cost too, as increasing weight requires stronger/wheels body, wheels, brakes, even engines.
There is a huge demand for higher energy density, preferably of a non-explosive kind.
