That number is more reasonable; given that they're assuming 5-year loans, and the average car in the U.S. lasts 14 years. 5 years is close to 34% of 14 years.
How do journalists get it so wrong? It's got to be intentional, or neglectful to the point of "I'm not even trying to understand; just tell me what to print".
I don't say this to be pedantic but to point out that cars across the board are more expensive than most people realize, and if you haven't bought a new car in a while, especially post-COVID, it can be a shock to see that a car with terrible infotainment, a cheap plastic interior, and cloth seats will run you $30-35k new. You want nice speakers? Leather (even fake)? A steering wheel that isn't made out of Fisher Price plastic? Let me know if you find something for under $50k new. God forbid you want anything approaching luxury like ventilated seats or rear seat climate control unless you're willing to drop $1k/mo on something.

But what is a reasonable percentile for someone to "comfortably" afford the monthly payment for a median new car? Maybe 80 is on the high side. But it certainly isn't 50%.
10% of income as a heuristic for a car payment isn't too terrible.
