Incidentally- there was no meaningful snow where I am, cm or so on pavements etc, roads fine- white at worst but easy driving. But I drove up the hill and holy ****, polished ice-encased deathsnow with just a little slush on top, some of the nastiest surfaces I’ve ever driven on. It can’t have been more than a cm or so but it was eeeeevil.
(which inevitably lead to an epic sliding session in the car park, until my car decided enough was enough and the ABS shat the bed because it couldn’t understand why the back wheels hadn’t turned for 5 minutes. Got to get me a rwd car even if I only drive it for an hour a year…)
Or, to put it more succinctly; just because you didn’t see any bad conditions doesn’t mean there’s none in your area.
