I'm a car expert

A CAR aficionado has revealed at least five secret functions of a vehicle's door handles that drivers typically never notice throughout their life.

The influencer and auto expert took to social media to share the various ways a car's door handle could be used aside from merely opening and closing the door itself.

"Did you think it was just for opening the door?" asked TikToker Wanchejiemei (@wanchejiemei) in a recent video.

"You're wrong."

"A lot of people drive their cars all their lives and don't know," he continued.

The car pro urged viewers to think of each hidden secret the next time they drive to make the process much easier.

Wanchejiemei's first tip for drivers was to keep an eye on the driver's side door handle in the left rearview mirror while backing into a parking space or garage.

When a driver sees the middle of the handle meet the curb or the steps at the back of the garage, they should stop.

Doing so gives them the perfect 30-centimeter spacing between the car and the edge of the parking spot or garage wall.

The car expert continued that the second tip involved adjusting the left rearview mirror properly.

Watching the driver's side handle again would help ensure everything is lined up for the best field of vision.

"When adjusting the left rearview mirror adjust the front door handle to the lower right corner of the rearview mirror," Wanchejiemei said.

Adjusting the right side mirror is the same process, flipped, with the front passenger side door handle moving to the lower left corner of the mirror.

For the third hidden door handle secret, Wanchejiemei explained that parallel parking can be much easier if drivers watch their door handle on the right rearview mirror when backing into the spot.

Paying attention to when the curb meets the mirror can inform the driver as to when they need to crank the steering wheel in the opposite direction to align everything.

"When the front door handle meets the horse curtain, turn the steering wheel all of the way to the left," he said.

Fourth, the car expert mentioned that the door handle on another vehicle could be useful in judging when drivers need to stop.

Wanchejiemei noted that if a car is dead on the road perpendicular to the front of your vehicle, any door handle on the side of the car that faces you could be used to know when to stop to prevent hitting it.

Once the handle disappears from a driver's line of sight in the windshield, it's time to hit the brakes.

The distance is a perfect 10 centimeters away, per the auto pro.

The final hidden use for car door handles could help prevent drivers from hitting other cars with their doors when they park next to them.

Wanchejiemei claimed that if a driver can see the door handle of the car next to them on a perfect horizontal line to theirs, it shouldn't matter how far they open the door — the two cars won't hit.

The car expert could be seen throwing his door open all the way, and it would not touch the other vehicle.

Fans were blown away by the hidden secrets the car expert revealed.

"AMAZING," one person wrote.

"Nice to know," another said.

A third added: "So TRUE."
