Drifting is when a driver oversteers,or the car exceeds its tire's limits of adhesion, to cause a loss of traction in the rear wheels, when the rear slip angle of a car is greater than the front slip angle. In doing so the front wheels point in the opposite direction of the turn, the car is going left but the wheels are pointed right. Every time we turn a vehicle we resist the change of direction due to Inertia. Simply put, inertia is the amount of resistance to a change in velocity or momentum. Newton's first law of motion connects to this because he said that an object at rest stays at rest or continue with constant velocity unless acted upon by an outside force. So an object will continue as it was unless some external force comes in and messes everything up. Inertia is most often masked by effects of friction and air resistance both decrease speed of moving objects and gravity.The friction between the tires and the road and allow the front wheels to break traction. Turning the steering wheel in the opposite direction, intertia of the car that is trying to slide in the opposite direction is added to the force applied by the engine and the friction of traction between the tires and the road. If the car is front-wheel drive, the rear tires weigh less so they break traction first which causes the rear to slide out. Lifting the throttle makes another weight transfer and enables the rear wheel to weigh even less. Such physics was applied in the movie Fast and Furious: Tokyo Drift. the main character had to master the physics of drifting to beat the antagonist. This called from some amazing racing/drifting scenes. Physics is everywhere whether we acknowledge it or not. But be careful when trying to drift - no saying that you should try, honestly I can't stop you- if the center of gravity is too high you will roll over instead of sliding.
