Modern purchase 60-90 days ago in our household. SUV with a umm a spare.
"
About one-third of new vehicles are not equipped with a full-size spare tire. Instead, many are equipped with a space-saver (donut) spare or tire sealant and inflation kit. Getting a flat tire is a major hassle and can be costly."
Many newer-model cars do not include a spare tire. Here’s what to know about spare tires, if you really even need one, and what other options are available.

I call a spare anything that can get you down the road however in the above link they mention a "space-saver." If a Tesla doesn't even have a space-saver that is even more reason to say HELL to the no. lol.
Oh and you stated "it's very rare for any new car .... to come with a spare tire." The article above says "one-third of new vehicles are not equipped with a full-size spare tire." But they have a space-saver. To me your generalization of "very rare" is not accurate.
To each their own. I feel sad for people who don't learn how to change a tire. Not even hating just saying it's sad to me. Oh well. I will carry on.
