Yeah those all BMWs and Mercedes NEVER get stuck in snow do they? And they defiantly don't get stuck while every other FWD car ever trundles past without drama.
The last few times it snowed properly I trundled past loads of stuck FWDs in a Jag or Merc (depending on year) with old summer tyres on. 90% of it is drivers being dumb and not allowing for the conditions.
One trick I've found in big RWD autos is to slip them into neutral at about 5mph when stopping. If not you can lock the fronts when going to slowly for the ABS to trigger & it'll just keep going forwards with the power from the idling engine going to the rear.
