To the second question: No.
To the first question: I'd have to ask them first have they read any of the faqs and/or guides on GTP. Followed by the usual explanation: If you're looking to drift you're going to need to learn a few things about it first. Drifting is not going to happen over-night and you're going to have to put months of work into just getting the basics down. (right here I'd have to ask them if they understand the basic turning structure of a drift, in case they didn't understand I would explain about the concepts of a countersteer and so on, but I doubt many people who are new to drifting really don't understand what a counter is if they've seen the car turn) There are 5 different tecniques that you will eventually know, the easiest one to learn will be the feint drift. It's named literally. Before the entrance of the corner, you feint to the opposite side of the corner and then counter that by turning back into the corner, and the rest of the drift comes from the momentum of the car. At this point it's relatively simple, when you're noticing the car is starting to get it's angle you'll need to initiate the counter - but note, everything can be explained, but all that matters is your own feeling of what's going on. Everyone has their own style and you need to be able to find your own style within the predominant ideas of a drift. Of course, the other drifts you don't need to worry about just yet because the drifts are not the easiest as you'll have to build up precise throttle control, and steering in order to accomplish them. Come back to me, or if you feel you have a better idea of drifting, go to the forums, when you can get a feel of the inertia drift.
Edit:
forgot to say, it's a lot different when someone with no clue or a little clue comes to you and asks you a question Nk4e, you can question their own knowledge so you have a better idea of where to start.
