Troubleshooting Ray Collision Node

Hi,

I’m trying to follow this tutorial (https://vimeo.com/203284769) where it uses ray collision node to detect intersection.
The subject is around 24min. For your reference, see a snippet of what I am trying to achieve:

Unfortunately, despite following the set-up, my scene doesn’t work the same. Are there any changes to the recent version that affects the ray collision node?

You can see my set-up here:

Instead of the wheel following the form of the landscape, it follows only one particular point of the landscape.

Is there a way around this?

Thank you for looking at the problem.
