To be fair, it's not just Google maps. I recently tried route planning on Viewranger on my phone, very quick, easy to use, great turn-by-turn cues, promt re-routing and...yes, technically this is path, if only I'd attached those handy hedge trimmers to my bike, and yes, I wouldn't expect you to know that there was a charity dog walk on Portobello prom as well as the usual hundreds of people, and yes, I suppose Musselborough race course is technically traffic free if you don't count the horses, and... FFS, how hard is it to develop something that actually just navigates you from A to B without f**king it up! Well, seemingly beyond the capability of any GPS device/software company on the entire planet.
