Vec, even with your usual jaundiced outlook, that posting has to take the biscuit. The whole purpose of an organisation set up to save life is......wait for it..... to save life. If it was a matter of cost, I can think of an immediate solution to save the entire cost of the project, as I'm sure you could. By the way, if you're prepared to take the risk with 4 airbags, I've had another brainwave - zero airbags should save you even more. Of course if you, like me, value your life and those of your loved ones, perhaps you should just bite the bullet and invest?
