Ever get bored while sitting in stand-still traffic in the city?

Well, those miserable commutes are about to get even worse thanks to Unnecessary Inventions, who invented a device that allows people to watch TikTok videos playing on the car in front of them with just a honk of their horn.

The device attaches to the rear of a car via a magnet and includes a screen and a microphone. The microphone is programmed to recognize a "honk" from the car behind it, and the input acts as a button to swipe to the next video.

The idea, according to the creator, was to make traffic ‘a little bit more enjoyable' by turning impatient honks into a way to interact with a TikTok feed mounted to the back of a car.

Now, there will be impatient honks mixed with doomscrolling honks … while the rest of us go slowly insane.
