I'm sure governments are willing to put public funds in to Galileo, just thing how much they'll be able to screw back out of the public when they use if for draconian road pricing schemes.

If they need money to pay for Galileo, why not tack on a one time liscensing fee to the price of the reciever units of €25 or something like that? It means they get money for the project and the consumer doesn't feel like they're being bent over and getting it in the backside.

Wouldn't work - if you add a premium to receivers then you'll kill the market - not that it will be big to start with.

Think about it, GPS receivers are mature and quite cheap. Galileo receivers are going to be new and expensive - so a limited market. If you add an extra tax and push the price up still further then you'll simply reduce the market further still.

If there's no prospect of a good market, you'll get no manufacturers supporting it, so no receivers being made to attract the tax.
