It would be easier to invent a better battery than to get landlords to do anything that wouldn’t maximize their profit.

It’s not that simple. In many countries the current electricity infrastructure can’t handle everyone charging their EVs. It’ll fry the wires. Countries like Finland have unusual advantage in this due to our grid being designed for electric heating, electric saunas and people using block heaters on their cars in the winter. This is not the case in most of the world.
