I do 100 miles to work and back every day and like to be safe, but quite frankly on the open road I quite often do 40k over the speed limit mainly when passing vehicles, and drive according to the conditions, I dont see this as a problem on a passing lane. I also dont go balls out unless I am on a quite road with virtually no traffic or at the race track.

People go fast all their lives and dont get killed, look at the Autobahn and other places where traffic moves along at 100mph plus. Drive according to the conditions and the vehicle.
In NZ people follow to close and dont leave adequate room to pass, drivers are aggressive, we have some of the worst drivers in the world. I have had on occasions had people speed up while I am passing them and the gap disappears consequently I am left with no option but to force my way in to avoid a head on collision!
My biggest fear is being hit by a drunk or asleep motorist.
