Most of us just assume that our cars come with a spare tire. One woman who drives a Honda Accord Hybrid recently learned that her vehicle does not have one. But it does have something else.

It took her three years to find out that there's an automatic tire inflator in the trunk.

Now Alliyah (@alliyahs.glo) is wondering why the person she bought the car from didn’t tell her.

“Fun fact, if you didn’t know, like I didn’t know. Currently driving a hybrid Honda, I don’t know if all of them have it," Aaliyah says. "But I know the hybrid Civics, and the Accords, if you drive any of those Honda vehicles. Check your [expletive] trunk before you go to that [expletive] gas station to get air in your [expletive] tire, [expletive]."

She says they all have automatic air compressors.
