But that is why we now have law that says that if you are responsible for lane closure on interstate, fines are going above $1,000. Directly aimed at A/S and A/T tire owners as it came out as compromise from proposed legislation to require actual snow tires (not just 3PMSF) after 68 car pile up on I70 EB before Denver where you have 8% grade for several miles and it was downhill.
That's a good solution. If you have multiple cars you don't need to get all fitted with winter tyres and if you can afford to stay home when it's bad you don't need winter tyres either.
