The tutorials in game don't seem all that helpful to someone new like me.

I came across this map: https://trackmania.exchange/tracks/view/779

And I really liked the concept. The concept he covered isn't particularly complex, but I would love to see something like that but for drifting or dealing with gear shifts.

I you don't know of any maps like that, just a simplistic map to practice a certain concept would be helpful too.

The TM School club in-game has some really good campaigns for learning the game.
