I was quite bullish on self driving cars about 5-6 years ago. As time passed by, and venture funding and media optimism seems to be drying out in silicon valley, I've been increasingly thinking level 5 is not going to happen in the next 20-30 years without significant legislative changes (e.g., dedicated roads or some other means of lowering the entropy for self-driving cars).
