Just as long as you can see the registered speed why worry where your going. I might have picked up North Yorkshire Mad Man Of The Week award by giving it all its beans whilst getting out of the way of a tar truck arsing about endangering traffic. I’m awaiting confirmation, postie has yet to come.
Sat navy’s have been responsible for more people getting lost since their inclusion in the first cars. People don’t know their left from their right & can’t count, “take the third left & you’ll be at your destination”. If your destination is to smash through a gate into a field full of pigs which are now running all over a dual carriageway then we’ll done.
Stick to Ordnance Survey, they’ve been at it for over 250 years, with just a pinch of Google Earth.
And the big plus know where your going & know how to get back. I know I said why worry at the header, but I recon you’re all bright enough to understand context.
