I disapprove of in-car sat-navs; I figure that if you need a little box dictating your actions then you deserve to be lost and alone. That’s quite aside from my theory that getting lost from time to time is good for the soul and provides a little bit of excitement and exploration for otherwise mundane little lives.
My main reason for disliking sat-navs though, is this. Have you ever been stuck behind someone who is paying absolutely no attention to where they’re going because they’re too busy peering at a glowing little box? I have, and they’re a fucking menace: random lane changes, sudden veering down side-roads before veering back, and endless-bloody-dawdling while they wait for something you plug into a fag lighter to tell them what to do.
My solution is simple. You either learn to plan your journey like any sane person, or you don’t get to drive – ever – because you don’t deserve to go anywhere.

I Don’t think you should blame the Sav Nav. I’d just put it down to 99% of people are just fuckwits!!

I’ve always found that a single side of A4 with a couple of extracts from google maps and a quick look over the route gets me from A to B without any problems. It’s always worked so far, and if it doesn’t, then I always have a decent roadmap to fall back on.
Hmm, you both speak truth, people are fuckwits.
