They absolutely promise this will not become a way for Big Brother to watch your every move, i.e., "No indeed. We would never let anyone but the fuel tax guys see your itinerary. Absolutely no chance we would let the cops and the other bureaucrats peek at it. I mean, +rilly+ +rilly+ rilly+!"
And your Social Security number can't be used for identification. And the income tax will never exceed 1 per cent. And your Grandpa voted for FDR because he kept us out of war.
