I think that EV (electric vhecles) and a small car are getting along well because they have same concepts like “not drive fast”, “not drive long distance” and “not drive expensively.”
If we don’t try to drive so fast, a car doesn’t need such strong steel.
The steel of “not fast driving car” can be made at half cost.
The shape of “not fast driving car” would be like a box-shape.
An equipment of a solar system could be put on its roof.
