If pass comes whenever you pass a car then it's clearly broken.
Same for turn. They don't happen every car or corner. It's broken I think. I. Can go minutes with no pop up even though I turn bunch of corners and pass tons of cars. It even says turn for like say 2 laps and not once pass. Things like that are what I'm curious about.
Speed feat comes up once you've gone above 180 and will subsequently reappear the higher your top speed, turn feat comes up whenever you turn a corner, a documented corner of the track that, perfect apex entry or otherwise, pass feat comes up whenever you pass another vehicle, perfectly or otherwise.
There's also the draft feat.
...slightly related, what I've found incredibly annoying is that a lap will be invalidated by an opponent drafting you. I understand why it would be if the situation was reversed, but how is another car drafting me affecting my lap?
If you mean that the AI is slipstreaming behind you, it will give you an advantage also. The airflow doesn't stop after your car, it will continue, so it gives you both an advantage. My English aint that great so I hope you understand. The wind leaving the car is pushed downwards, back towards the car and up again. That is creating a 'sucking'-like something. (sorry). So when someone is driving behind you, that is happening to the car behind you, so it'll effect both.
Edit:
I hope this works for you!
