Smoothing terrain for a vehicle game?

[Velatieren]

I am making a vehicle-based game (cars/motorbikes) and the standard terrain that gaia generates is much too wrinkled and the vehicles at high speeds tend to bounce around. The terrain should be smooth after Random generation, so the movement is much more pleasant..  How can I achieve it?

Yes you can smooth the terrain. 

If you open the Gaia Manager, go to the advanced tab, tools, stamper (if you dont already have one). 
Then after adding or selecting the stamper, please change the operation type to smooth. 
You will want to use small values, until its right for you.
