Right. Conditions vary from day to day and from street to street. That's why preparation is so hard.
I've ridden a few times on slushy streets on Citi Bike. That is definitely an improvement. The bike is heavy, and the riding position is upright, and the tires are wide. Also, the drum brakes work well and are unaffected by weather.
