Is this a white car thing? White reflects heat, methinks. So relatively warm perhaps for a fly on a cooler day?
Umm, not quite. White reflects heat so doesn't absorb as much heat as a darker-coloured object. Put a white object next to a black one in the sun and the black one will be warmer.

I was thinking it might reflect heat onto the flies rather than the surface being warmer for their feet. Interesting subject.

White is very bad camouflage for a black fly,  but flies do prefer some colours to others, and avoid some colours

Some people will only consider you an expert if they agree with your point of view or advice,  when you give them advice they don't like they consider you an idiot

So those with the white interiors, keep your windows shut :)
Let's be careful out there !

A neighbour a few years back had a MINI in Volcanic Orange. The files loved that.
