In aviation, pilots struggle with that. Pilots have a duty "to see and avoid" in VMC, which means visually scanning outside the plane 90% of the time. But it's human nature to fiddle with instruments and displays. So even in the steam gauge era it was a tough balancing act, and now it's much worse with acres of cockpit electronics. It requires more training, and one would hope ADS-B provides sufficient collision alerts, to offset the heads-down tendency. One of the best illustrations of this is the Qantas A380 in-flight engine failure that resulted in 1,000 or so alerts. They had to be manually acknowledged before the systems were cooperative again. One of the pilots was completely occupied with that task alone.
