How to activate physics in Matinee?

Hello everyone!

Is there anyway to activate physically driven objects in Matinee? I’ll explain better: I’ve done a seuquence in matinee that involves trucks moving: I’ve decided to use Vehicle template to have them react to terrain when travelling.
Everything is working fine, but to see them move I need to PLAY GAME in viewport, cause playing a simple matinee moves everything EXCEPT the vehicles.

I’ve keyframes on Throttle and Steering for all the trucks, I’ve managed to do it in a proper way, but there is a way to see them move playing simply the Matinee?
