Driver's Ed is stressful enough when you're behind the wheel and attempting to not run down pedestrians, but it becomes instantly more stressful when you have Ice Cube and Kevin Hart yelling expletives about your left hand turn skills. 

In an attempt to scare one of his staffers from ever getting behind the wheel again, Conan brought in Ice Cube and Kevin Hart to chastise one of his staffers who somehow made it into her 30s without ever learning to drive a car. 

Ice Cube also made sure to impart practical safety advice along the way:

"Tupac was one of the biggest thugs I know, and he always wore his seatbelt." 

They also made sure to stop by a medical marijuana dispensary, because that's just something you do when Ice Cube is in the car with you.
