Thanks. For those interested I used two off the shelf assets for this. I used the car system from the Game Jam Starter Kit and the Waypoint Circuit system from the Unity standard assets with A LOT of modifications. All the rest of the coding is original. The buggy was a free asset from Thingiverse that I made a capture script that rendered the buggy from all the appropriate angles. The camara work was done through Cimiemachine. It's totally worth learning to use if you haven't yet.
