I think that's the issue,not only that but riding on snow,especially compacted or icy roads,shared with motor traffic my worst fear is being hit by out of control cars driven by idiots,without appreciation of conditions or going down in front of one,only for the driver not used to such conditions to panic,hit the brakes and skid into me.
I witnessed a typical example of driver idiocy a couple of days ago on a wet potentially icy motorway in sub zero temps where almost all traffic was reduced to sub 60mph,to be overtaken by a Golfalike who was doing 75mph+ and if that wasn't bad enough his nearside front wheel was a spacesaver emergency spare wheel which are rated at 50mph max
.
There's no accounting for loonies and there's more than the fair share of them driving cars.
