In a world in which we are all about to become back-seat drivers, autonomous vehicle developers are working to let passengers know what the car sees and comprehends as it moves.
Many surveys over the past few years have shown that consumers are skeptical about the safety of self-driving vehicles. An Axios/Survey Monkey poll in October showed that about two-thirds of those surveyed said they felt unsafe around autonomous vehicles. A AAA survey in May showed similar results, with 73 percent saying they felt too unsafe to ride in self-driving cars and 63 percent saying they felt unsafe near them.

"It's about gaining trust, and the way that we do that is by making sure there are a lot of communications in a lot of different ways back to the person in the car," said Tisha Johnson, Volvo's vice president of interior design. "In a good relationship, over-communication is a good thing."
