Every few weeks or once a month. In the winter it's tough to find a good touchless carwash and I don't like to do it by hand when it's so cold out.
It protects the paint and finish. That means the car can go longer without having to be repainted, and in many cases it increases the resale value. Not sure what you mean by "leave that nasty runoff somewhere it shouldn't be". What's on the car usually comes from where it's driven - the roads. When you wash a car, the runoff usually goes to the same place it'd run off to on the road. It's not like leaving the stuff on the car is somehow better for the environment.
