Well... I don't have a driving license.
And when I sit in a car, I actually seldom listen to kpop.
But yesterday, I was sitting in a car together with someone, and you could listen to Spotify in the car, and he let me listen to kpop songs in that car. (It was a lot of ATEEZ songs and then also the TNX song "Kick It 4 Now")
It has happened to me a few times though that a kpop song was playing in my country's radio channel, while I was sitting in a car.
