I got lightly snowed on most of the way home, but it's not settling at all, and in places the ground was basically dry! It's above zero, about 1°C, so that's not really surprising.
Interestingly some parked cars seems to provide a better platform for snow than others, and were quite white. It could have been that some cars were warmer from when they were running, but by this time, most cars should have cold down to the ambient, so I guess it's just different "stickiness" and textures of some paints.
