[insightfully]

Came across this video for the Accord, with note in the comments that it can also be accessed on the the Insight using an alternate button sequence. (This video tip is from the same person who posted steps for the Accord infotainment screen reboot which we use for the Insight. And a downside is that the radio doesn't operate while in this mode.)

Activation Steps:
1 - Press and hold 'HOME + BACK + VOLUME' buttons on the Insight (vs HOME + VOLUME + SOURCE on Accord) until screen changes and/or beeps
2 - Select 'Detail Information & Setting' --> 'Guideline Setup' --> 'Rear Wide Camera' --> choose 'Fixed' or 'Dynamic' Guideline
3 - Press the red 'Return' button to exit this mode when done using.

Possible uses (?):
- As a substitute for rearview mirror
- For monitoring an aggressive driver behind you
- Wider rear view while driving than LaneWatch provides
- Monitor a hitch and/or towed load
- More time to live in the past and/or enjoy what's behind you

The video below illustrates the function on the Accord:

I sometimes would like that option just to see how close the car behind me is tailgating. Too bad this needs to be done in the diagnostic menu which I prefer to stay out of(fear of messing something up).
