IMO they should just plaster the place with cameras. We have family at Jollies Lookout, they had a huge land slide during the rain event in Jan 2013. Since then, I've averaged 3 days/month up there so I feel I know the road well.
My observations:
*If I push through at 5-10km over the speed limit, I nearly always have someone appear out of nowhere on my tail. How guys can sit on 100+ is beyond me, the number of times you round a bent to find a cyclist doing 5 up a pinch is unbelievable....
*Quite often while working up there it sounds like we are at a grand prix track - seriously it goes for several hours / day
*pretty much every week there's a fresh set of marks where someone has run out of talent...
