Rain rolls off the roof

okay i am doing good i do not smoke in the fast but over here it is cold when it rain and it is not cold enought to put the heater on and the windows fog up so i like to crack the window a bit to get the fog to go away but me if it is raining and i want a smoke i will just pull over and get out of the car and smoke i do not care if i get wet just as long as i do not smoke in the car

i was so bad at english the teacher kicked me out and just gave me a c so i do not have any good english...

does anyone have any fixes for the rain rolling on the windows do they have the rain shields yet???????????????
