First I've heard of the suggestion that the cost of a car should be 50% of annual pay. To me that's insane, but then again I view my car as an appliance[0].

A 2020 yaris starts at 15,650. With fees, should be around that mark.
The problem is, the median US household does not buy a Yaris. They spend more like double that. So 30-40k PER car, two cars per household.
And it seems obviously extravagant to me for a middle class family to have two new cars. One maybe, but two? But even so, by the formula, the family can afford two $30K cars.
Such a family would not want to spend more than 49K total on their cars. so that is 1 car for 49K or 2 for 24K
and that IMO should be the extreme absolute limit
