I know a couple. They will happily drive their car after having a glass
of beer, but the same people would never think of flying a plane after
the same beer.

Why do they make the distinction? Car accidents are much more common than
airplane accidents, and typically 50% involve alcohol. How do they justify
driving under the influence of the drug? And if they think it's okay, how can
one be sure that they won't make the same mistake when flying?

Apparently many other people think they're different.

Yes. That's why so many people die in vehicular accidents after consuming
alcohol. They always think they are special.
