That is why I have an automatic car with every possible accessory such as cruise control, automatic headlights, automatic wipers, electric seats and windows, heated seats (I don't like a cold bum!) parking aid &etc. I work enough without having to do while in the car!

Paradoxically it is easiest to get lost when visibility is really good, i.e. > 100 miles. I've seen this happen... Navigation in the air without obvious landmarks to navigate by is very, very difficult, but even then well known landmarks can in fact be misinterpreted even by skilled people. Its really *never* a trivial thing. Note that people like the RAF had specialist navigator schools until relatively recently, and navigation was a very hard earned skill, even until the 1980s. It remained so until the advent of GPS which has had an absolutely dramatic effect on navigation in the real world, and continues to do so. Look simply at "smart" weapons. The other thing that has influenced civil aviation (and pre-dated GPS for civil aviation purposes) and made it more accurate are inertial guidance systems, which largely derive from the development of things like ICBMs. The cost of INS systems remains high however. GPS systems are not only accurate but cheap. -- I'm not apathetic... I just don't give a sh** anymore ?John Wright

No I've never been a professional driver and nor do I want to be. I love driving, thanks to all the gadgets in my car. Sat Nav is great and I'm sure that in the future there will be a way of connecting it so the car drives itself to the destination with the driver only having to intervene now and again, rather like a autopilot on a plane. As you dislike modernity so much why do you own a car when you have two good legs? |
