Even greater reason to be 'defensive' rather than impatient!
Nonsense,the facts are there was a covering like dandruff,a goon was doing 10mph on a road with a 60mph limit,cars going the other direction were all travelling at 30mph plus and there was 99% more black of the road visible that white with the 'dusting',it was also daylight 3.15pm and the car temperature was showing 3c.
There was a line of drivers behind the goon doing 10mph of probably 15 cars.
Travelling at the speed of a golf buggy or even slower was not needed in any way no matter how much you would like to paint it.
