I’m pretty sure most cart games use basically the same or a similar cart. For example, this model and this model are pretty good models you can utilize.
This one also has pieces of track you can clone, although the scripts (if any) will most likely be updated as it was uploaded in 2015.
I got your point, but i mean I need the carts they use in cart ride around nothing, the ones where you press W to go forward and high chance to fall off
You can’t expect to find exactly what you want in the toolbox.
I’m almost willing to bet that creators of models that work perfectly for their successful game aren’t just going to publish parts of it for others to use.
Roblox is a site where you can make exactly what you want. That’s it. Period.
If you can’t make something yet then you need to learn how to make it. This means you can use models from the toolbox, but you have to modify them to work the way YOU want.
Also, broaden your search terms.
Try train, or tracks, or something different that might be similar so you can learn different aspects.
