In the article they noted this was the same for millennials and gen x before them. I'm going to assume the standard for youths purchasing cars was with the baby boomer generation. I know my dad told me when he was young, you would purchase a cool car that didn't work for the equivalent of $100 dollars, get a friend to tow it home, then work on it for a few weeks to get it running. He told me how much he missed his MG Midget, which let's recognize as a cool ass car for a kid to have. He could fix that car with a wrench, a stick of butter, and a deck of cars*. All his friends would be doing the same.
Nowadays it would be a $1k junker, and you'd need to have a computer science degree to fix the onboard computer while having all the specific tools to get into their proprietary parts. There are older cars too, but the standard of fixing a car has increased, all the while each generation has less time and money to do it.
This was a typo, but I love this typo. You say deck of cards, I say deck of cars, Thank you @otp@sh.itjust.works !
