I don't see a problem with that.
If I was an average person with little confidence driving on snow/ice covered roads, I would ask a taxi driver. They are experienced, professional (well, most) drivers and are likely to have some experience of bad weather driving.
Plus, with the inexperienced drivers off the road, it would be safer for us all.
Off topic, but related, this week I've seen an alarming number of posh folks with high end 4 x 4s slowing down to 1 mile per hour just to turn a simple corner.
