In all fairness a non-trivial number of vehicles don’t even have a spare tire these days much less a full-size one. And the stock jack even SUVs come with is often next to useless.
Having to swap out tires is pretty unusual in normal driving these days and it’s not like you carry spares of everything else that could break and strand you in a car. So I sort of understand it even if I don’t really like it.
I have had a tire totally self-destruct within the last decade, so I feel like I still need a spare. I don't believe that once a tire is damaged at speed the cans of sealant are likely to work, since it will probably tear apart.
I also have AAA, and don't intend to change a tire if I don't have to, but AAA will not provide you with a suitable tire and wheel. And I don't see why someone would want to arrange for their life to depend on their cell phone working if they drive anywhere out of town.
In fact, right now, I have run-flat tires, a spare, and AAA.
