Many transits are actually flexible, and people can react to weather and traffic conditions by postponing or canceling their plans. Often, that's exactly what happens completely independent from the transport options because, for example, any outdoor activity is going to be less fun when it's cold and rainy. If you somehow get people to try, they also discover that biking in really bad conditions is actually quite a lot of fun, provided you are wearing the right clothes. In the cold, your usual jacket is almost always enough because you're exercising anyway, but you'll need the best gloves and hat you can find. The days where I got to work in a snowstorm are actually my most productive :) The real problem in bad weather conditions is that the threat from cars is amplified: it's usually dark in winter, snow and rain further deteriorate visibility, and snow/ice are dangerous because both bikes and cars are less predictable. Bikes are also extremely vulnerable to blocks of hardened snow that often get shoved right onto their usual path by cars.
