@thebegin10 I know that it should be relatively easy to code, the only problem is I have zero knowledge of any coding language.

By the way, you can find examples of that checkpoint in videos by Broughy1322 titled "Random All".

Hi, I was wondering if someone could make a racing checkpoint which randomizes the vehicle if you drive through it. You'll be able to choose whether you want the car to be randomized from a specific class or just from every car. Maybe you can also hook it up with Map Editor for easier placement?

It is basicaly the checkpoint which randomly changes the car in Broughy1322's random races if you drive through them.
Think of the random vehicle spawner in Menyoo, except you can exclude certain vehicles and vehicle classes.
