I&#x27;d like to be more optimistic than I am because it would be great--disruptive economic ramifications notwithstanding. Personally, I suspect that we&#x27;ll hit a certain plateau--say, freeway or other select road driving under a certain set of parameters (which is still a big win) and find that getting to the true general-purpose case is a really tough and long slog.<p>I&#x27;m sure we&#x27;re going to get there. The question is whether it&#x27;s one decade or five to have no human present under a wide range of conditions.
