I live on a rural road, drive a 55 mile commute across the peak district to work and was recently hit head on by another drive who drifted accross the road into my path, I also see a lot of accidents on my way to work - particularly in winter. So maybe I am biased.
BUT in 5 years of rural commuting I have learnt that once you factor in other road users, people pulling out, tractors etc, trying to drive at a faster pace makes little or no difference to your arrival time, but a much higher difference to your stress levels and likelyhood of an accident. It is a fools assumption that it is either beneficial or safe to do so.
As I posted up thread, last year I was hit head on at 35mph, by a driver doing 30. At a combined impact speed of 65mph, 3 months on he is still in hospital - at a combined impact speed of 120mph we would both have died at the scene.
I was doing the school run - no children on board at the time thankfully, and it wasnt my fault - he just drifted accross the white line into my path.
It really doesnt matter how good a driver you think you are, it can happen to anyone - but if you dont think it could happen to you, you are fooling yourself.
So, based on my experience, my advice is to take a chill pill and please slow down
