It's a bit like driving through the Black Spur in outer-Melbourne, it's a fairly long stretch of road consisting of a sh!t-load of bendybits, curves and whatnot, yet, the speed limit is marked at 100kmph, but there's no way you could sit on 100kmph through there without ending in the trees, but it still encourages you to try
half of the time you cant even go past 60 in it, and perhaps it promotes nasty driving...
but some times they need to make proper speed limits
