When you go up the bridge at 160, how do you know that there will be nothing on the other side of the bridge - I've seen broken down cars on there, trucks travelling slowly, traffic entering from the roundabout below, and in the mornings the traffic from decoration roundabout can be backed up to the bridge.

At that speed it will be impossible to break for the unexpected.

That's the reason the speed limit on that portion of the road is 80 - because there is NO visibility.

If you *really* must go so fast, pick a road with better visibility, not a road where you can't see what's ahead due to the rise and fall of the road. Try a road in the middle of the desert somewhere, or better yet, grow up and stop driving like a teenager.
