Just another hoax issued by a government-funded institution to discourage all those who are doing serious research work.

40 square feet of usable surface on a car?

40 x 50 watts x 5 hours of sunshine = 10 kWh.

At 0.3 kWh per mile you could drive 30 miles. That would work for a lot of people. The US average driving day is just under 35.

Probably would continue to make more sense to hook the panels to the grid and charge off the grid.

I don’t drive much, so with 50% efficient solar cells on the roof and bonnet of a small car and sunny parking spots I entirely power my day to day driving with solar. Of course, living in Australia helps.
