To achive Multidrifting, you need to drift multiples times, and each of them need to be pretty close together. To do this, you need a way to link the drifts. This are the ways (in the order I discovered) to drift in this game.

--------1.- Turn Drift-------- (Easy, Turns)

This is the original intended way to drift in this game. You drift before a turn, and take it Very Clean. Avoid doing this drift for too long, since this just don't conserve speed. Move to the next ones.

--------2.- Autocanceled Drift [AD]-------- (Easy, depends of the road to work, Straight road)

This drift abuse the road to perform a drift, and the game canceling the drift for you. After the drift you are free to do another one and conserve the drifting speed (since you only need the beginning part).

Kenya championship is a road where you can easily AD.

AD = Drift. You don't even need to release the aceleration button.

--------3.- Snake Drift [Manual Drift]-------- (Hard, can be perfomed everywhere, Straight road) (This is kinda hard on your hands, just be careful if you have a hand condition)

This drift abuse the system way to check if you are able to do a drift. By turning you car to the left, you will be able to do a drift to the right. After the beginning of the drift, you will need to release A and re-ajust your car. (Cancel it manually) (This can be done from right to left too)

You can conserve your Drifting Speed in almost all the tracks of this game if you dominate this trick.

The most prominent (and early) example of Snake Drifting is Italy Championship.

--------4.- Mid Drifting-------- (Dificulty vary from Medium to Real Hard, only way to conserve Drifting Speed in long turns)

This kind of drift is a child of both, Turn Drifting AND Snake Drifting, becuase you need to do a drift MID turn, cancel it, and do another one.

In most of Cruis'n The World tracks, it going to be pretty easy to do, since their turns are not that sharp. But on Championship is where the dificulty to do them goes up significanly.

Real Hard Mid Drifting: Kenya Championship have 2 pretty heavy Mid Drift that take a good time to dominate, but that is the only way to conserve your Drifting Speed for a whole lap.

Medium Mid Drifting: Italy Championship is pretty much Mid Drifting and Snake Drifting all the way.
