That’s another clickbait-style hook, not a real claim by itself.
“I didn’t even know this was a thing, but every driver should know about it”
This kind of line is used to:
- create curiosity
- suggest a “hidden secret”
- push people to click “see more” without giving details
What it usually turns out to be
In car-related posts, this phrase is commonly attached to very ordinary things like:
- How to use a parking brake properly
- Tire pressure warnings or dashboard lights
- How to check oil or coolant
- Emergency kit basics
- Fuel-saving driving habits
- Using recirculation/AC settings correctly
Sometimes it’s useful advice—but often it’s just basic driving knowledge presented as “secret information.”
Reality check
There is no single unknown “thing every driver must know.” Safe driving knowledge is well documented and widely taught; viral posts just repackage it to sound hidden or dramatic.
If you paste the full post or describe the “thing,” I can tell you whether it’s actually useful, outdated, or misleading.
