Urban evacuation fails when everyone decides to flee at the same time
The perfect plan exists: a cheap house in Somosierra, a car within the first hour of the alert, a bike along back roads if the highway jams up, and on foot, a hidden bivouac halfway there. That's 7 hours by bike and 24 on foot, with a minimal backpack. The flaw isn't in the routes but in the timing: half a million neighbors may have had exactly the same idea.
From car to bivouac: the scale of the collapse
The car is the fastest resource and the first one to seize up in a mass exodus. That's why some argue a prepper shouldn't depend on a vehicle; others accept the window of opportunity but know it closes within minutes. Scale changes everything. In a megacity, every exit is the same funnel. In a Spanish city of 50,000 inhabitants, there are a thousand possible exits and panic doesn't turn into a traffic jam.
The unsettling fact: the planning itself assumes that, if the surprise is total, all that's left is a bivouac halfway there with whatever you're wearing. The city doesn't trap you for lack of exits. It traps you because your neighbor has the same map as you.
