There is a toll on essentially all of the highways in Austria. Perhaps
that is where the tunnel money comes from. Also, Austria is a transit
country, and they collect fees for lorries etc passing through (which is
only fair, since they are using the roads).

Americans coming to Europe often remark that the price of gas is high.
However, for most people the total costs for a given standard of living
are what is important, regardless of how it is divided up. Obviously,
if one doesn't have to save money for health care, college costs etc,
it's easier to pay for things which are more expensive here. Of course,
a car is more of a luxury item here in that it is possible to live without
one, which is not the case in most areas of the US. In many areas,
one is better off without a car. It's just a different perspective.
Remember the European soldier who met a cannibal? The former said, how
could you kill people just to eat them? The latter replied, how could
you not eat people whom you have killed anyway?

Actually, the average American probably spends much more on gasoline than
the average European. (In England, gasoline is "petrol", gas refers to,
well, any gas, perhaps carbon dioxide, depending on context. Reminds me
of an Englishman (true story) who walked into a bar in the American
midwest and ordered a glass of water with gas. Thinking it was a joke,
the bartender replied "Will that be unleaded, sir?".) The average car
uses much more fuel than the average car in Europe, and even big cars
here get pretty good mileage. Add to that the fact that people don't have
to drive as much. (Something else: in all of Germany, over 80 million people
and no speed limit, there are about 3000 traffic deaths per year. I think just
the state of Texas has about twice that.)

I think the large majority of mineral water in Europe comes from Germany. Yes,
you might occasionally see Perrier or, at an Italian restaurant, some Italian
water, but most is local.
