Some kid reading this thread might go out and start "popping the clutch or gassing it hard" (whatever that means) or try to "carry a lot of speed or make sudden jerky movements on the steering wheel.........or ...... use the e-brake".
By popping the clutch in you are shifting weight, the same applies to sudden throttle input. In our FWD cars, the necessity to jerk the steering wheel to transfer weight or jounce the suspension into a slide is much more apparent. This can be proven at any auto-x or road racing track. The same applies to trail braking, yes weight shifting is what occurs in most situations to convince the car into a slide.
