While increasing energy efficiency and available space, both of which can be used for extending EV range (by adding more batteries that deplete more slowly) - one of the biggest EV issues right now.

Or you could just fit a mini party bus inside a hatchback, whichever you prefer.

To your point though, one of the othe big EV issues is cost (both purchase and maintenance) - even if a large chunk of it is artificial. Wonder what the price tag and lifespan on these things will be.

EV maintenance cost is quite low compared to ICE vehicles. Brakes and suspension are probably the biggest wear items, but brakes have comparatively less wear because of the regen braking.

Nope - the ~~ADAC ~~ (turns out, i was wrong about that) GDV in Germany did a study a few weeks ago and they found EV maintenance is actually higher, because parts are so much more expensive and also brakes are needed a lot more regularly. However, the last one could be just a german problem, because of our TÜV.

That study says nothing about maintenance but is about repair cost after accidents. Those are 1/3 higher for EV because also small damages to batteries can increase risk of fire and batteries are also more readily exchanged due to lack of experience of the shops.

Everyone is talking about breaks while the study doesn't say anything about that.
