ive been drifting since GT2, but back then i didnt know what it was, my cars didnt have TCS so i just let them slide through the turns and eventually i just did that with every race.....
then i got my ps2 and GT3 and still had no idea about drifting, i remember having an ATRA NSX and i took the tcs off so i could do burnouts...i realised my car slid again, so i went with a month or so of grip racing.
then i started to e-brake my 10024hp R34 around midfield and i got pretty good at it, yet i couldnt keep the car sliding.
so i moved back to my ATRA nsx and on the huge turn before the straight on complex string i started drifting without even knowing it.. i came into the corner full speed, and back then i thought that slamming the car into reverse as i was sliding helped keep it sliding....
anyways, cut to 5 months forward and now i can drift almost anything in the game, let alone every track...
sims, slicks, normals i got it all dialed down, i can do just a good a drift with a pair of sims on a stock FD as i can with a pair of slicks on my spoon s2k.
although i know i will be doubted, and not belived untill i get some kind of video up in here....4wheel drifts are a normal thing for me, ive mastered and conquered them, in tracks like trial mountain, deep forest, midfieldII i dont even countersteer...
im getting bored of drifting in GT3 since i feel i have completed every challenge i set out for myself, so now im renting other racing games to see what they can do for me.....
untill GT4 comes out.....ill just keep on drifting the same old same old...
so to answer your question, i gues i never did practise, it was just always there...
peace
