This is a good point. Really good ideas can overcome legislative and regulatory inertia, with enough money and time behind them, thank goodness.
My only devil's advocate point would be that drive-by-wire cars typically have mechanical failsafes that the average person is fairly comforted by. For example, many drive by wire systems have some springs that set the car to just above idle if the ECU gets confused. I guess the analog for a potentially opaque windshield is sticking your head out the window, though this may not be fast enough if you're on a windy mountain road, driving through construction, etc.
A liquid-crystal-less region at the bottom of the windshield may do the job, and still do all the information-displaying and sun-blocking you need.

What happens if a bug in your modern, fly-by-wire car decides to mix up the gas signal and the brake signal?
