Re: windscreen wipers?
I agree. No need for windows at all. Or if you do have windows on your self-driving car, see if you can get some Peril Sensitive Sunglasses like Zaphod Beeblebrox had. Designed to help you have "a more relaxed attitude toward danger," they turn darker as peril increases. About the time your car goes off that hovercraft ramp, they should turn completely black.
