I’m very glad that you’re OK, Chris.  What about a helmet cam?

It’s a known phenomenon, Chris: your high acuity vision works only with a 
stable image and since it is only 2 degrees wide (approx) you have to move it 
to the right place and dwell there to see a small object like an approaching 

If you merely sweep your eyes around the scene your vision will perform 
"saccadic jumps” and you’re likely to miss small objects unless there is 
relative movement.  And if you’re on a collision course, you’ll remember from 
your flying days, there is no relative movement.

Our vision is deeply flawed and we need to use it with great care and 
deliberation, flying or driving . . .
