Last time in full snow a 15 minute commute took 1hr15. I physically couldn't go any faster due to rear wheelspin! I was going sideways up speedbumps, too...
Well done. Got stuck in my street once. The slight snow covered rise had been compacted so much it was ice. Thought I would take a run at it but there were cars and kerbs etc around so thought better of it. I would have got past it but chances of stopping were slim.
