Sitting at drive through and driver headrest exploded and hit me in the back of the head. Thank God I was not moving at the time and my car was in park or I may have wrecked! Startled me and I was dazed and confused because I couldnât figure out what had happened! This just happened a few hours ago so I have not been able to report it or have it checked out. I did take several pictures. There were no warnings or anything and it just happened as I was sitting there! If I had been driving, it could have been catastrophic! My neck is sore and I have a headache.
