Google maps? GPS guidance with senic routeswith no thought about access, narrow roads, impassible lanes.
On a recent holiday in the Isle of Wright, Google tried to send me down narrow lanes 6' 6" max or lanes with grass in the middle, mostly on an indirect route! Why when the relevant A, B or C road was direct and quiet!
I use GPS for quidance ( set to female voice, easy to ignore) - I have a couple of rules for car use... Dont go down a lane with grass in the middle, dont go down narrow (6' 6" limit) lanes and mostly dont use a lane with a hgv ban.
Why? 'cos coming the oposite way will be a t-what in a wide speeding 4x4, a tractor/hgv/bus!!
I stopped using google on the iow - the cars built in system gave better routes.
