I have a flexible commute that sometimes involves driving a car into the zone and if I see snow in the forecast I'll be less likely to be in the city with a car that day.

I love congestion pricing, I will gladly pay $9 if it lowers traffic during peak hours. I also try to plan trips in the offpeak hours anyway. If you leave at 11pm you can get from shea stadium to Philly in an hour forty-five.
