I agree with Cees that we don't want to make more work for the officials but the speed limit that Les imposed in Motegi did just that and as such I don't see it as a viable solution for that reason alone.
My idea of harsher penalties is aimed at moving the pressure onto the pilots to comply. If there is no collision then there is no work for the officials and we can zip up an down as fast as we want/need knowing that if we cause or are involved in a collision then the slower we are going the safer and cheaper in points it will be.
As strange as it sounds, self preservation does not seem to be a strong enough deterrent. To some of these guys the points are all that matters. Even the low altitude bumps happening at targets are showing that right now they have no problem doing it right in front of the officials.
If the penalty was there on paper then maybe they would think twice about it.
Also just put this panorama together from the last cash prize flight - Gosh I hope we get to go back there....
