A car that passively recharges using solar is always superior to one that doesn't. I don't care if it only charges 5 miles per day. Just the fact that if you're stranded just a few miles from help, or to stave off charge losses when parked for a long time, or to power connected car features when it's off without draining drive battery, all make this make sense, and every EV should have at least a consideration for a solar panel on the hood and roof if not a glass roof.
