And I'd hardly blame the Sat Nav, if it says turn, I'll glance at the map on the screen, then look ahead and relate it to what I see. And act accordingly. After all SatNav data does go out of date (mine used to try and send me up a bus lane if I was using it to come back from somewhere*
*not the units fault, the bus lane was a bright idea by the council that appeared just after I bought the unit. It has since been removed as it backed up the traffic further then before, and the only reason the traffic and buses get backed up is because the council made a temporary diversion permanent so less traffic passed their offices... so they won't solve that problem in a hurry
