We were getting quite good at thinking about the tractor that may appear, the amount of pheasants on the road, the steep damp narrow roads, the areas of loose gravel at the bottom of those hills, and how our grip is affected by all of these.
In a few months time, we might also have to think about the possibility of;
being blinded by the sun, low in the sky, as we come over the crest of a hill,
driving round a corner, straight into a deep puddle lying across the road,
deer moving from woodland to grasslands and dawn or dusk,
patches of fog in the bottom of dips in the countryside,
icy sections of roads, where the sun never reaches the tarmac because it is in the trees,
the list can go on, and could be endless.
Tyres are designed to be used at specific pressures on specific cars, to produce the optimum amount of grip.
Windows are designed to be seen through. If they are dirty, or covered in snow or ice, or misted up on the inside, you won't be able to see where the road goes, and what the next hazard is.
Lights are designed to shine brightly, but if they are covered in mud, frost or snow, they cannot do the job they are there to do.
Drive safely, expect the unexpected, and be ready to react to whatever may be next.
