Episode Details

Daniel drives in Jerusalem and trusts the blue line — until it puts him nose to nose with a delivery truck in an alley built for one car. His question: how does a routing app actually work under the hood? This episode unpacks the three layers behind every route you've ever taken: the static map, the routing engine, and the live conditions layer on top. Along the way: why a map is really a graph, how Contraction Hierarchies compress a country's road network into a skeleton your phone can search in milliseconds, why "avoid tolls" is a tax but avoiding Area A is a wall, and why that gap between the map and the actual road is where all the trouble lives.
