I managed to really properly get the Jag sideways yesterday, pulling (carefully I might add) off a minor road onto an A road down a slight hill I pulled up the road (turning to my left of course) which back-tracks the route of the other one slightly, as I wanted to go to the fuel station, rather than following the route across the road to the other carriagway where I would say 80% of the traffic goes, so I had a big sea of slush and a bit of compacted snow to drive through before I got onto the A road proper, and when I did that I had to try and get away with a little more urgency than the absolute crawl I'm usually forced down to in this weather, well anyway, you can imagine and indeed I had an idea of what might happen.
However, there was nothing to hit so off I went anyway, I entered the main carriage way with the back end of the car in the right hand lane and the front in the left

...I bet I looked pretty cool though, an 18ft black Jag going sideways showering the central reservation with slush and such, I'd be lying if I said it caught me by surprise, I knew what was liable to happen, I also may have possibly found my finger in the vacinity of the DSC button, and it may have had some ...contact
Slightly less fun was the fact that I couldn't actually pull off my own drive earlier, I had to dig my wheels out somewhat and then use sand driectly under my rear wheels to get any traction to get off the damn drive.
Typically though my assessment of the cars snow capability so far, is well ...awful, really awful, albeit not quite as bad as my old 330Ci though. The Jag heats up faster too, which is nice.
