As a pitch for self driving, it's going to be a long time before I trust a computer to do the above better than I do. At the very least adding sensors I don't have access to will give me assurance the car won't drive into a wall with a road painted on it. I don't know how on earth you'd market self-driving as competent without being absurdly conservative about what functionality you claim to be able to deliver. Aggregate statistics about safety aren't going to make me feel emotionally stable when I am familiar with how jerky and skittish the driving is under visually confusing driving conditions.
Perhaps vision is sufficient, but it seems hopelessly optimistic to expect to be able to pitch it without some core improvement over human driving (aside from my ability to take the hand off the wheel while driving).
Edit: hilariously, there's already a video demonstrating this exact scenario: https://youtu.be/IQJL3htsDyQ
