why do i have anxiety when i get into a car?

I’m 16 years old and I don’t have my license or permit yet, so i dont drive. When i get into the car i get a high anxiety once we hit the main street ways. Why do I have it and is there a name for my anxiety?

It is only known to individual conscience. Or it may be known to those people who are very close. I have to consult my good friends before I try to choose a best name for that.
