1) Marketing/PR for autonomous vehicles needs to really drive home their safety, so when you hear “robot car,” you think “… saves lives.”
2) Is it hard to imagine the opposite fear in children born 10 years from now? Having seen mostly robotic cars in real life, and human-driven cars getting in accidents on TV and in movies, might the child of the future react with terror when the robotic chauffeur intones, “human driver detected, approaching from rear”?
