We should hope it never works as half the reason for building it is so they can stick a black box in every car and aircraft, force us to buy them then charge us to use them and finally bill use for miles driven/ flown
GPS would be completely adequate for that already, regardless of what happens to Galileo, if the political will were there to do it.
More generally, I'm not sure that the fear of being tracked/billed is a proportionate reason to hope that satellite navigation technology goes away. It's a modest downside, and one that is politically difficult to achieve because we live in a democracy (insert laughter as required, but c.f. China/Iran/etc.) making it hard work for the rulemakers to introduce unpopular measures.
Set against that, satellite navigation brings its users quite a big upside.
