Good write-up about a phenomenon I’d never expect to matter in a car. In aircraft it is the norm for mid-air collisions to occur this way. For example, https://en.m.wikipedia.org/wiki/Hughes_Airwest_Flight_706 https://en.m.wikipedia.org/wiki/Hughes_Airwest_Flight_706 but there are many others. Aircraft in the US now have autonomous transponders broadcasting their location to each other. The author overlooks this fact since the “pilot training” to avoid this problem actually does not work very well. The pilot training is to take advantage of services that can alert you to other traffic, such as Air Traffic Control.

> The author overlooks this fact since the “pilot training” to avoid this problem actually does not work very well. This is critical in the context of the author claiming that drivers should be expected to recognize the risk in this situation. Pilots are required to undergo significantly more training and expected to be much more methodical about operating their vehicles than drivers. In spite of all that, they're not very good at watching for this kind of scenario either. Instead, a combination of air traffic control, transponder-based traffic warning systems and the fact that air traffic is vastly more sparse than road traffic make collisions between aircraft rare events. If a particular intersection design causes collisions, the primary fault should be considered to be with the intersection rather than the drivers.

  IIRC CBDR is not really in the FAA PPL curriculum at all. I only recall a quick mention from my CFI when I went through it. It's much more heavily emphasized to military pilots as missiles are designed to predict an impact point and fly towards that rather than the aircraft (lead pursuit) so pilots are trained to determine if a missile is maintaining guidance towards them by seeing if it appears stationary in space.
