True, driving routes wasn't a great example. But I think the point stands if you take something like the way they drive (number of vehicles, how they manage junctions, etc.) or which exit they use. You can observe stuff like the way police motorcyclists (I think they call them 'outriders') speed ahead to the next junction, stop traffic, convoy passes through, rear motorcyclists meanwhile catch up to the front of the convoy and the ones holding traffic then adopt their position at the rear, swapping each junction. But there's no benefit to documenting/publicising that (and I'm sure there's nuance to it I haven't picked up on). It's probably also easier to get involved in the police and go on that advanced driving course or whatever and learn all about the techniques they use than it is to actually be assigned to that team - it's not super secret, but the more you keep hidden the harder you make it to be subversive.
