We were doing the "natural" speed on the way to Qld. in the XF, but I wouldn't have been doing more than about 100k in my FE Holden years ago, because it wasn't up to it even on the same road although it could go a lot faster.
That is the same as when me and my GF drove to canberra. She sat on 130 cause thats where she felt safe and thats where I sat most of the time but on one stretch of the Hume Hwy I took it up to 150, cause it is a new section, it is flat as hell, and there was ample visibilty. If my car could do it, I would've wound it up to 180.
As for officially determined speed limits, we've probably all encountered yellow advisory signs which are so far above what is safe as to be dangerous and so far below what is safe as to be ridiculous. If you can't judge the speed for an corner you're approaching and have a clear view of, you shouldn't be on the road. Unless, of course, it's one that some alleged road engineer has carefully put negative camber on or a nasty tightening radius to catch you out (or both in some cases), in which case there shouldn't be roads like that and the road and not speed or driver ability is the problem.
This is one thing that I think cause most accidents.
They really need consistency with this.
There is a corner on the way to my GF's place and it is posted at 55 however I have been around it at 85 comfortably and could go more if my car handled better.
And then theres the on-ramp off the west gate freeway onto the tulla. It is posted at 70, but in my car I only feel comfortable at 65 and even less in the wet.
I think is where some people get un-stuck, everyone is so used to being able to go over the recommended cornering speeds, that the ones that are correct or even over-correct will catch people out, and bingo, there's your accident.
