In theory it works nicely. In practice, not so well. A good rule of
thumb is one horsepower per square yard of fully-illuminated area. A
car that requires twenty horsepower---which is pretty low by today's
standards---needs an area of solar cells at least nine feet by twenty
feet.

Working solar cars have been constructed. They require extreme
lightweight materials and aren't well-suited to a Sunday drive with
the family. More like "one person, 10-20 mph, as long as it's sunny."

Someone may pipe up and say "but you can use batteries and charge them
when you're not driving". That's done with the experimental cars but
there's a very carefully-calculated tradeoff in weight and
performance. Take a look at this car:

Not much room for anything but a driver.
