+10 on the tire track, makes snow riding much more bearable. I find the cars are much more forgiving the crappier the weather gets. Not sure if it's them being considerate of the poor basid on the bike or just extra fearful of running over someone that might slip and fall. Either way ... I'll take it. I've been know to pull over on some sections if it's just too sketchy with piled snow and rutted ice and wait for a clear spot in traffic. Worst case I'll sidewalk for half a block to clear the grossness. Pressure is on the City to do a better job plowing, as in consider winter cyclists. Losing 1.5-3 ft of curb lane in the winter bites it.
