You can, I think both were described in the theory book for notorcycle license when I glanced through it. Fun fact: when I read about it I had to test and I had to make sure I wasn't deceiving myself so I put one palm in front of the handle on one side and the other one behind the handle on the other side. That way I could ensure I pushed it the correct way. It worked exactly as advertised (50cc bike so somewhere below 60km/h). Much simpler than using slow motion camera etc.
