Seem like the greatest solution, these EV can also act as battery storage for renewables.

    That's tricky though. Would you deplete it during night to have it empty in the morning? Wear expensive battery? Plus, I assume, car is disconnected from grid for most of the day (i.e. when you are at work).

    But you park it at work there could be slow AC charger, to slowly charge it when you are away.

    Placing solar on rooftop of car also seem as good idea

    "solar-powered cars" have been tried many times because it's a great headline, but the math never works. Cars simply don't have enough surface area to capture a lot of solar power. The amount of energy is low enough to not be worthwhile, except in the most extreme edge cases.

    Yeah a day you can get 2% of battery, but this would make extend range and make it more susteninable considering rooftop and hood space is always unused

    2% is probably near the theoretical maximum, too. Actual output considering weather, efficiency losses, etc is probably less than half that. Solidly in "not-worth-it" territory for most use-cases. Heck, my car won't even properly charge on a 120V outlet when it's too cold, because it needs to heat up the battery to a safe temperature first and at -20°C that takes more than the ~1kW available from the outlet.
