TPMS essentially automates people checking their tires because the reality is most people do not do a walk around on their car before driving.
In theory, we could use a dipstick in our fuel tank but most of us prefer an automated gage.

I had a rental Mercedes with a leak in a tire recently... a tire was at something like 15psi but looked visually the same as the other tires. I absolutely do a walk around on all of my rentals and take pictures, but I would have had no clue if it weren't for TPMS. I would have driven it until it failed.
