Black cars…Also not a great choice for the Aussie sun. Absorbs heat.

I remember watching a televised oval-track truck race a few decades ago; one competitor had to drop out because his truck developed vapour lock from the heat. The bonnet was black.

In the next race his truck had a white bonnet. A pit reporter with a pyrometer took temps of that truck’s bonnet before the race, plus another truck with a black bonnet.

The white bonnet was 42C and the black bonnet was 82C – just sitting there in the starting lineup, with engines off.
