We have a phrase at work that I think applies here: "chronic unease." It means to take a step beyond understanding your situation, surroundings, work processes, etc. and asking yourself, "what could go wrong?" It sounds like you have great knowledge of your route, traffic patterns, etc., but do you ask yourself "what if?" I would guess the answer is probably yes. That is a good habit to get in. Make a conscious effort to ask yourself, "what could go wrong?"
