I gave up trying to do a King Canute a long time ago and just accept "progress" has good, no so good and bad points. For me, (and for many others of similar vintage) the issue is learning how to use new technology and what the various acronyms not only stand for their meaning too! More often than not I find, and I suspect a good proportion of other smartphone users are the same, it is the same when you buy a new washing machine with umpteen programmes and end up using one or two.......
It was bad enough learning how to use a slide rule at school (yes, I'm that old) but now computers are 2nd nature to youngsters even my 6 year old grandson puts me to shame And I have seen Adrian (the OP) at work on computers and it was just mind-blowing how quick and simply he used photoshop and posting on here, so I am not surprised he sees this latest aid to keeping in touch on the move as another useful bit of kit that will help his lifestyle.
So I am afraid those of you who condem the use of gadgets in cars are showing your age..... but will you admit it? Sure, anything to help safe driving I'm 100% in favour and absolutely no excuses for those not using hands-free. But honestly if you get so wound up up about the Navdy I can recall similar concerns about when radios/cassette players were introduced. And then we have drivers who are more concentrating more on animated conversations in cars or turning round to see if little Joey has wet himself - there are a whole host of potential distractions that for me are more dangerous than a gadget to stop what drivers doing what they currently do (we all see the hand texting and phone to the ear going on everyday) and not keeping their eyes on the road.
And how far away are we from driverless cars on the road anyway - God forbid The thought of a computer driven car on our roads scares the shite out me bigtime as I fail to see how any technology will ever react in the same way as the human brain when something out the ordinary happens and has not been thought about by the programmers.
