I don't see it often either, but my government has been very active trying to get people to do bi-monthly tire pressure checks at the very least.

I don't think most people know how to do it, to be honest. Partially because people seem to think reading two pages in a manual is some kind of sisyphean task that no mortal should ever be cursed with.

It's pretty crazy how little people care. Even if you don't care about the safety aspect, keeping your tires inflated well saves you a ton on fuel and tire replacements.
