Most Useful/ Useless Car feature

[*bfine32*]

There was actually a feature on my 2020 Equinox that almost got me in a fight.

A couple of years ago the weather suddenly turned cold and all of my tires lost a few lbs PSI. I got my tire gauge and went to the 5-Star to use their air pump. As soon as I pulled in another car pulled in front of me.

I started to fill my back passenger tire and after a couple of seconds I heard a horn beep, I thought to myself "I know this dude is not trying to hurry me".

So I went (slowly) to my back driver's side tire and as I'd been filling for a couple of seconds the horn beeped again. I said to myself if he blows that horn one more time there's gonna be trouble in the 5-Star parking lot.

I took my time moving to my front driver's side tire whilst "mean mugging" and began filling it. After a couple of seconds, a horn beeped. That's when I realized it was my horn. Apparently, it beeps the horn when you reach the recommended PSI.
