Self-driving cars will always have limitations. It's just not possible to make it ready for all kinds of road or even off-road surfaces. Fast-forward into future, if human-driven cars get banned, there will be no reason for self-driving cars to have manual controls and the only option for car will be to refuse to go into a situation it can't handle. I very much believe in gradual improvements and that is what many large car manufacturers are doing. I can easily imagine not needing to control my car on a highway, in a city, or when parking it, but I expect the manual controls will stay there for a very very long time.
