Behavioral and pattern analysis is always in full overdrive when I drive. I drive in Africa, people never follow rules, red lights at crossings mean go for bikers, when there are no lights you can't just give right of way, or you'll never move. When nearing intersections, people accelerate so they can cross before you, and it's a long line, and they know you have right of way, so they accelerate to scare you into stopping. Amateurs freeze and hold up the line for a very long time, usually until a traffic officer shows up to unblock (multiply this by every intersection). In order for you to get anywhere, you have to play the same game, and get close enough to the point where they aren't sure you'll stop, and will hit you and will have to pay. So often at crossings you're always in near misses and they realize you're not going to stop, so they do. Everyone is skilled enough to do this daily. Your senses, your risk analysis, your spider sense are fully overclocked most of the time. And then there are all the other crazy things that happen, like all the insane lane zig zagging people do, bikers our of nowhere et night with no lights, memorizing all the pot holes in all roads in the city bc they aren't illuminated at night so you can drive at 80-120km/h, etc. So no, it's not just your eyes. Lots of sensors, memory, processing, memory/mapping are required.
