Seems some of them are nearly suicidal...

Drivers following satellite navigation systems through a village called Crackpot have been directed along a track at the edge of a 100ft cliff.

Cars, minibuses and trucks have taken the steep, twisty road from Swaledale to Wensleydale in North Yorkshire.

When vehicles become stuck, drivers are reversing perilously close to the cliff edge, say worried locals.

Carol Porter, 39, who lives at Summer Lodge Farm, said: "We want this sorting out before something terrible happens."

She said that she and her husband Steven, 41, who live next to the track, have been helping at least one driver a week.

"When they get grounded on the small boulders, were having to go up there in the tractor and pull them out," said Mrs Porter.

There is also a video somewhere on the Beeb site, TBH its only suitable for 4X4s as it says in the rest of the text.

Tbh, the sat nav system knows as much as we do when we look at a road on a map.  Its a road.

At the very most it tells you how high it is or if its on an edge.  It doesnt tell you what it is suitable for.  It is down to people teeling the sat nav comapnies to update their mapping database to know what routes are not suitable.

If your local and know a better route, just ignore the sat nav and let it work out where you are going.

Still funny though...  

remember once the sat nav decided to take me down a single track road over the blooming motorway,
got off one juntion early and ended up going on a magical mystery tour as it weaved over the motorway twice  :shock:

Done that sort of thing a few times trying to get onto the A66 from Stockton, a normal road map is useless.
