didn't the government want to make winter tires the law in Quebec for the winter because of this?? I remember it being big news last winter.. don't know if it was passed as a law, but there's too many people out there driving on bald tires in the snow.
As for a 2004 Corolla on snow.. my buddy last year almost rear-ended someone on his LE during one of the big storms we had.. he missed the guy by about an inch. Unfortunately the SUV behind him didn't brake on time and rear-ended his car so hard that it deleted his trunk and it drove the LE far under the car in front. Thanks to his insurance he now drives a Corolla S.
