Don't know how deep your snow is, or well cleared, but in 10 years driving smarts I've never had any trouble. But then I do slow down in snow
Even in heavy snowfall in Germany, without winter tyres, there were no problems. The stability control and traction control did its thing just fine.
Coming home on Monday night from Scotland, we went through a thunderstorm and there was a terriffic smell of diesel - I reckon there was fuel on the road.
My wife's Peugeot* 1007 was all over the road and she had to slow down to avoid being pitched into the barrier - my smartie was just fine.
