I agree that there are lots of useless things in cars, but the tire pressure sensors on my base trim 2013 Honda recently saved me a big headache.

I recently pulled out of a business and the "low tire pressure light" turned on right away. "Hmm?" My next stop was 1/4 mile away, and it still felt okay. At the next parking lot I checked all the tires with my gauge and found one was 10psi low. On closer inspection the nail was right on top. Sure enough I'd picked up a little nail. It was a slow leak, and I wouldn't have heard the hiss. If not for the sensor I might not have noticed I'd gotten a flat until I got on the freeway.

PSA: Check your spare's air pressure. Mine was supposed to be 60psi. It had 40psi, which was good enough to get me to the tire store. I checked the spare when I got home - the tire repair crew had bumped it up to 55psi.

My dad was leaving on a trip recently. Because 'spare tire psi' was on my mind I checked his spare - it was only 25psi.
