I've gone out in the morning with water on the windows and might take a paper towel to try and at least wipe most of it off, but inevitably some sticks to the window and it's not ideal. Plus it can be really cold. So I got a squeegee for $5 and toss it in the back seat floor. It's been so much better than just using a paper towel. Even if it's raining, it's better than having a mass of drops sticking to the glass.
