Why don't you just quote from your book to support your arguement. Also if you've watched Initial D they drift at low speeds, the game just exaggerates everything, also grip is faster than drift, whilst you can drift at high speeds grip is still faster, hence why the worlds best drivers (i.e. those in Formula 1, Nascar, TOCA etc) all use grip. It's true that rally drivers drift, but due to the conditions of what they race on its hard to maintain grip at those kinda speeds. Drifting isn't slow, it's just slower than grip in most cases. I guess most people say exhibition drifting because they know drift isn't as competitive as grip, so they try to show style in races which people like to see anyway, and most people still win racing exhibition anyway, so don't say it sucks, a lot of people who think they're drifting fast are just losing traction when they slam the gas around the corner because they haven't developed their style yet.
Anyway what's any of this got to to with the topic "inertia drift" ?
