Has to be a lot safer than my normal navigators i.e. Wife and daughters.

Pip (mum) is great. I've yet to get it through to her that while I can understand instructions like "take next left" or "get in middle lane", I can not understand her pointing and "go that way". I've no doubt it looks right to her but from my angle in the driving seat she can look to be directing me between lanes, into on coming traffic, etc. Peter (dad) could give instructions like left or right but (even before his stroke - he's worse now) left can mean right or visa versa...

My favourite navigational error though was not caused by them and Pip was the driver. We were trying to get to a party after a session and our navigator was a bit vague with lots of yes/no... The confusion winded up with Pip jumping red traffic lights and it turned out there was a police van behind us. The teetotal Pip was breathalised. I saw the funny side but she didn't.

I'm on L plates in a car but when I had motor bikes, years ago, my method of navigation was just to look at a map and write down the names of towns and roads I'd need to be aiming for. Never had a problem, except trying to find the end of journey in a town and I guess that's the only place I would see sat nav as being useful.
