Racy!
But seriously, seeing the older people made me realize that those guys wouldn't have even had cars all over when they were growing up.
From Wikipedia:
"The modern car—a practical, marketable automobile for everyday use—was invented in 1886, when the German inventor Carl Benz patented his Benz Patent-Motorwagen. Commercial cars became widely available during the 20th century. The 1901 Oldsmobile Curved Dash and the 1908 Ford Model T, both American cars, are widely considered the first mass-produced and mass-affordable cars, respectively."
(First gasoline car at all was 1808 though)
So this was at most around 21 years after the Model T. For anyone much older than that, cars would have been rare at best when they were young.
