It’s not really, we took this off-topic a bit. With regards to the OP that had to do with peripheral vision which is an interesting topic, It was hit upon a bit here: A Mongrel of a Map?
A major role of peripheral vision, by comparison, is to monitor a much wider area, looking for regions that appear interesting or informative, in order to plan eye movements.
Given that it makes sense that something in you peripheral vision could “catch your eye” as that’s it’s function. As was mentioned driving is a mostly a simple task. If brake lights catch your eye it’s just a matter of looking up and taking the appropriate actions, like slamming on the brakes. At sea it takes a bit to regain the entire traffic picture when in heavy traffic.
