There is black-and white reasoning about this because the maths around "what is the surface area of the car, how much charge can it generate and how far can it go on that charge" is also black-and white. And not favourable.

As the other reply says, this is not "the debate of electric cars"; this is the debate about this specific electric car design, with the solar panels on the car.

It's not talking about the current argument. It's saying the current argument shares the property of arguing against the use-cases of people outside the target demographic.

People who argue "electric cars will never be viable" (and not anyone in this thread) commonly complain about lack of supercharging speed, despite that being a feature that most people (and all initial adopters) will only use once or twice a year, if ever. This will not be a problem for a long time, as right now only ~1% of car users have an EV and that won't be a major problem until we start running out of ICE car-owning EV buyers who don't need that, which is at least at the 50% mark.
