For me the conversation in the example sounds artificial, it is obvious that the friend did not get what you mean. If I’d had such conversation, I’d have added something like: “If I go, sure I can pick you up. But I’m not sure when I’ll go” (or “I’m not sure if I’d go at all or at what time” if you really are not sure)
