Here's how to learn how to drift.

1. Buy a rusted out, primered '78 RX7 for $125
2. Find a very, very large empty dirt parking lot
3. Practice for several years (be prepared to pull your car out of ditches, from around trees etc.
4. Keep it off the streets, I don't want you to knock down my mailbox

but seriously, its really fun, just don't ever do it around anything/anyone else. Start on dirt/gravel, then try wet pavement. Its hard to do dry pavement without a good rear/4 wheel drive car.
Never do it on a road.
