I definitely agree that in principle a computer can drive with cameras alone. I don't know whether it's a useful statement. Like a human can determine the genre of a movie merely by watching it. I wouldn't suggest to blockbuster in 1990 that they should collect no genre metadata for movies because the database server should automatically sort it out on its own. (Nowadays somewhat feasible with ML of course, but 20+ years later.) What sensors/data you need is a question of where computers are now or will shortly be, and it seems that for now they need the extra structure of LIDAR for best effectiveness.
