Question about the "Driving template" example (where are the events?)

I use the examples to learn so when I find a template with only one line used on the event sheet and no behaviors used on the cars I wonder how the template works. How does this template work with only 1 event?

Barrier have solid behaviour and car have car and scroll to behaviour.

Just with car behaviour you can move.

ok thanks. I didn't see the car behavior installed. Must be blind. hehe.
