^^ This. The stock Toyos were actually pretty good accelerating on ice (didn't try stopping though). However I always use winter tires and will never go back. If you can afford a vehicle like the CX5 with AWD... you can afford winter tires. Actually in places with significant snow everyone should get winters.
True, and this is why they are mandatory in Quebec starting December 15 of every year. Every province in Canada should do the same IMHO.
