(This is dath ilan, and several excellent movies - scripted by highly intelligent writers partially supported by the will of Civilization to help produce public goods - have started with somebody hearing a voice inside their head. Everybody who sees a movie like that will know, as a matter of cliche, what you ought to do conditional on the voice inside your head being real.
And if the voice isn't real? Then you ought to do the same thing for different reasons. It may not end that way in the movies, or at least not nearly as often, but those positive incentives have also been arranged and publicized.
The blacked-out car isn't there as cruelty, to scare her, or to prevent her from seeing where she's going. She knows where she's going. And cruelty above all is something that dath ilani would never tolerate from their government, for hurting people is wrong.
The blacked-out surfaces are there to prevent other people from seeing her, if their own automatic cars pass her by. After all, if the voice in her head was real, that would definitely be a gigantic unknown-magnitude infohazard situation. People who hear voices in their heads and believe them real will accordingly do what they think they must, to act rightly and protect others. Their path can and should be eased, especially in the direction Civilization wants them to take.)
