Fuel is cheap
Can you name another liquid, apart from tap water, that is cheaper?
Think about the steps involved to get it from the ground to the pump, I mean think about how hard it is to build a platform in the North Sea
which then drills down... way down to get the oil. Then you've got to refine, store and ship it all over the world.
And it's cheaper than orange juice.
The other amazing thinig is that you can buy a machine, brand new, for around $13,000 - with warranty
This includes a stereo, air bags, remote locking, alarm etc etc.
You can then put 4-5 adults in this machine and travel at 100kmh + for hour after hour, the cost of which is about 10c/kilometre!
And all this runs on the cheapest liquid I can think of. It's even cheaper than bottled water. I think it's bloody amazing.
Edit: Distance between Sydney and London is about 16,000km.
You can get a one way ticket for around $1600, or 10c/Km.
That's you and your luggage
flying at 1,000kmh for 10c/Km.
Now I'm thinking perhaps we are all spoilt
