Before the Journey · Principle 3 of Six
Build enough familiarity with the route to understand where you are going.
Familiarisation is a brief review of the journey so that its shape is already in mind before it begins: the general direction, the main roads, the towns passed and the few junctions where a mistake would be expensive.
It is not memorising the route. It is knowing enough to recognise where you are.
A driver who knows the shape of a journey hears each instruction in context. “Take the next exit” means something when you already know the road it leads to.
The same driver can carry on when the screen freezes, the signal drops or the battery fails, because the journey was never held only inside the device.
