Absolutely, this is the best advice in this thread. In the event that I lose track of what's behind me, I will even sometimes go as far as intentionally varying my speed a bit to get something to go around me so I can re-establish a complete mental picture with 100% certainty.

Or maybe use your mirrors or shoulder check instead of flying blind.

Thanks for the snarky but uninformed reply. I will edify you: There are some vehicles in which mirrors and should check alone are not enough to get a complete picture, and the only way to know what's around you is to keep track. Large RVs, trucks towing large trailers, etc. all fall into this category. Sedans, compact crossovers, and large SUVs with decent visibility are all comparatively simple to drive.
