Racing Game Pre Pro - Stunt Brainstorm

I came up with a few stunt ideas that I would like to incorporate somehow in my track.

I like the idea of narrow tracks a lot. It adds so much chaos. So this idea is a narrow alleyway or something, and on either side there are jumps with flat platforms extending past the jump. The diamonds would be where triggers are placed. Actually, only one trigger that alternates back and forth between the two jumps. If someone jumps and successfully hits the trigger some alleyway junk or something would fall, slowing down the players behind. I also wanted to add some kind of ledge at the end of the platform, so if you don't hit the jump right you could not make the whole thing and get stuck.

In my previous post I posted a clip from CTR that was in a tunnel. I was thinking of this kind of thing from the beginning. It would be a tunnel where you could wallride. At the trough of the tube there would be some kind of material that makes makes it harder to drive in and is kicked up obscuring people's vision behind you. On either side there would be some narrow jumps with boosts that would be hard to land right, but if you did you would get to drive on a ledge not having to worry about other drivers or that bad material. Originally I wanted this to be placed as players are coming out of a turn, making it harder to hit the jumps. But as I was brainstorming I thought it would be cool to do something like this:

This space would be fairly large in actual driving space but be littered by obstacles placed strategically to make it hard or challenging to navigate, with a few viable paths. The x's indicate a trigger that if hit one of the dark horizontal bars would be activated and shoot out of the ground blocking that path for a second. I thought it would be cool to have this bigger space lead into this narrow tunnel, so people are fighting and converging on the same space.

Coming out of the tunnel I want to have a big jump that leads to a raised platform with no guard rails. There would be paths below in case you fell off, but it would be faster if you stayed up top. There were a lot of Trackmania 2 tracks I played that had a part of the track like this. I thought it was really challenging, and would be really fun if there were multiple people colliding. I also wanted players to come out this tunnel on this big jump and have this big reveal, like everything opens up, maybe some bright sun stuff happening.

These are just a few ideas but I feel like there is enough text in this post as it is.
