So this was last night after a few hours in the saddle. Had just come back onto bitumen road after doing a favour sent us a few kms down gravel.
The bloody thing would not get out of the way. I tried Low beam, high beam and even beeping the horn. Had a learner and a freaking out wife on 2 more bikes behind me. Eventually when I went around it went between the other 2 bikes.
This is the closest I have been to a Roo on the road (although earlier in the ride i had one suddenly appear beside me on a corner) and was a bit worried he would turn around and ram me or knock me off the bike somehow.
Might look into a set of the plastic Roo Shoes. I here that they work better for unicorns as no one has seen one of them while riding with them.
