I will take your word for it. But I never fill air in my tires (and I suspect many people are like me). I bought the present car three years ago; I never filled air in the tires.
Just last week I had my routine maintenance, I was told that all the tires are in great shape. No uneven wear, etc. plenty of tread still left (I assume they rotate the tires during regular maintenance). In old days, when inner tube was not very efficient and air used to leak out, it was important to top up. I don’t think that has been necessary for years now. I would fill up air only for extraordinary circumstances, such as getting a puncture (or I replaced the tire with the mini and mini does not have enough air pressure).
These days inner liners are very good, have very low permeability, and usually it is not important to top up the air. I am not even sure what is the status where I live, whether they charge for air or not. To me, this is a non issue.
