I was driving my bimmer normally down a semi busy road and when I looked at my engine temp. it was all the way up on the red! I began pulling over and as I was I heard a huge pop noise come from the engine, immediately after that white steam/smoke began pouring from under the hood. I turned off the car instantly put it in park and popped the hood. Within about 10 seconds the steam/smoke was gone. As soon as I got out of the car a man who was smoking a cigarette outside of Mcdonald's ran up to me telling me that he has the same car and the same thing happened to him. He told me I didn't want to hear what he had to tell me, it was the head gasket. So right after that I closed the hood and we got a few other people help us push the car into the parking lot. I called a tow truck and they came within 60 min I had them tow it to a mechanic by my house that is trustworthy.
