I started running a helmet cam in 2014 and saving highlights of some of the more interesting commutes/rides.
The most remarkable thing about it is how poorly I perceive events while I'm riding. I believe the combination of adrenaline and vulnerability (vs cars) distorts one's perception significantly. Upon review, close passes by cars seem less close. The timing of near misses seem much longer. The order of events may be remembered wrong by the end of the ride. Vehicle makes, models and colors are often perceived and remembered incorrectly. General threats to my well-being seem less threatening.
What is remembered correctly are the emotions, especially in the case of accomplishment and reactions to beauty.
