Which isn't "critically dependent" unless you remove the pilot.

This seems just slightly nuts. Cite?

By the way, use Google and an argument of oregon gps tax to find lots of
references including some in CA and other places.
It is all very stupid since it claims to equalize the road maintenance
and then rewards heavy gas guzzling cars. Look like GM could be behind it.

Bear in mind that a very large percentage of new cars already have GPS
fitted these days.

You yanks have it easy. How do you think we converted from gallons to
litres a couple of years ago? :-)

A similar system has been mooted for the UK.

By the way, the tax would probably be collected quarterly or
something, not by collecting it at the pumps.

Which country has approved GPS for even a CAT I precision approach, let
alone CAT III (autoland). I know of none.
