While traveling down a highway at 60-65 mph, roll down both back windows all the way, and maintain 60-65 mph. Keep the driver, front passenger, and sun roof windows closed. After doing this, let me know if you experience any sort of discomfort, such as sore ear drums or the feeling that your roof of the car might come off. Please note this is not a joke.

 

I did experiance some kind of airpocket thing that bothered my ears while i was in florida when i had my drivers window cracked open just a little bit but it was only in florida and i dont have a sunroof.

 

That is common in any car. Certain combinations of windows open and close hurt my ear drums in my truck and my Neon too.
