Our correspondent in Dublin, Mick, has kindly sent us a blurry close-up which might be a candidate for a mystery car competition.
What is remarkable is that among our readers are people with the skill to recognise what this car is without having seen one in the metal for what could be years. This says something about how much visual consistency is applied at all scales of a car compared to a building, for example.
I would guess that if you pick 1% of the surface of a car and 1% of the surface of a building then the cars would be easier to identify. Another interesting point is whether a car from today is more or less easily identified from a 1% sample compared to one from, say, 1960. That’s a researchable question!
