, assuming you don't wind up utterly baffled or with a headache!

I always loved the idea of a HUD-type display that could display lots of info - a bit like IronMan. You look at someone and up comes their details. You're driving and you can see your velocity and the velocity of other vehicles, combined speed, road conditions, hazard highlighting etc

William Gibson did this a while back in the book 'Virtual light'.

In the end, it's not going to be spectacles or contact lenses, it's going to be direct input into the optic nerve, or possibly induction of signals direct in the optic centre of the brain. However in the mean time, I'll have a car with a full HUD thanks .

I recall a company trying to do a HUD type display for all cars that displays more than the speed - things like g-forces, acceleration etc. Can't for the life of me remember what it was called.

There's been a few cars in the US with a HUD - the '88 Olds Cutlass Supreme had one.
There's numerous phone apps that'll apparently reflect info onto the screen for you. I've downloaded a couple but I've not tried them out yet.
