Next bus to Altrincham delayed by Windows Defender

There was a time when catching a bus meant knowing how the local network worked: a dog-eared timetable or encyclopedic knowledge of routes and numbering systems was required before you even got on board. Modern mapping apps now bake in bus guidance, and route data flows freely from web services. The rather excellent kit from UK Departure Boards, for instance, can show bus services just as happily as rail departures.
