When a samurai in service accompanies his lord on a journey and they arrive at post-station it is most important that he should before sunset take care to make enquiries of the people of the locality, and note any hill or wood or shrine or temple and take his bearings by them, and find out in what direction from their lodging there is an open space and what is the condition of the road. This should be done so that should a fire suddenly break out during the night and it be necessary for his lord to retire he will be able to lead the way and know where to guide him. And when he accompanies his lord on foot, to remember to go in front of him on a hill and behind him on a slope may seem a small matter, but it is one a retainer should not overlook. For it is the duty of a samurai to be vigilant and careful at all times to think out how he can render any possible service in the calling to which he is appointed. – Daidoji Yuzan
This passage brings to mind how we should not be just “going through” the motions when we carry arms for a living. How many coppers have been caught flat footed when that “routine call” turned to shit? Think ahead…find those points of cover in your environment…have some sort of mental “what if” plan that covers as many options you can think of as you approach that car stop.
