Irish country roads - Sign-Nav is still better than Sat-Nav

I have been using sat-nav on and off for the past 3 years, I am still convinced that navigating by signs is better than satellite navigation. The simple reason is that half the country is still dug up due to new estates, bypasses and motorways and the maps haven't caught up.

Where Sat-Nav reigns supreme is the city as sign-posts are a rarity. When driving cross country you are still better off following the signs as sat-nav has and continues to send lorries up and down boreens so as to save 1 km on a journey.
