I was thinking of some sort of modification of this which would allow the user to make waterslides/mat slides. Basically, the track is simply a semicircular channel (The banking and such would stay, but I also had another idea: Perhaps changing how much of the track is generated, so you could have covered track/tunnels or even narrow track) Pressing E while facing the track would spawn a mat at the beginning, which you'd sit in, and slide down the slide. But, I'd also like to see realistic physics with it (For example, the mat flying off of an uncovered or unbanked turn when moving too fast)

Customizable track width is a must, I'd also like to see both dimensions of the track customizable (Width and depth, to make flatter channels or deeper channels, or just larger overall)

I'd like the mats not to explode if they fall off the track (Particularly for making waterslides which end in lakes etc.) Preferrably, they'd just get deleted if they hit the ground.
