Well the upshot of snow tires is you can pass those slow pokes, even if the passing lane isn't plowed... Dad was coming home from work last winter on a fresh set of blizzaks in his cobalt, came up on some slow moving traffic, signalled a pass, and around he went... Turns out the vehicle he just passed was a police car. Flashed his red and blues for a second then turned them off (guess he realized he was nowhere near the speed limit...)
