Discription of Events: The people in the car were loud, pulled right along side us to our speed, yelled "grandma" and threw a handful of change through the car window and sped off. It was a male driver with multiple people in the car. It was a passanger & the back seat had so many people that they all were lapped up! Specifically i saw a white or pale light skined female on someones lap behind driver looking directly at me while i took down license plate. They were recklessly driving as well. It was very unsafe & i hope they be careful & dont act this way again. They as well as us could have lost our lives.
