So it cannot be objectively true that London is the capital of Great Britain, because I am assuming that there are capital and countries and cities, and goodness knows what? If a statement cannot be objectively true because there are assumptions then no statement at all can be objectively true. Is that what you are saying.
Pretty much, but I would say that some statements, such as "one plus one equals two", are objectively true, unless we play around with language.

Of course whether a car or plane is dependent on where you are going. But the statement that you cannot go to Europe from the United States by car so, by default some other way of getting there is better than by car is objectively true. Of course, I am not making the vague statement that traveling by car is better than traveling by plane (etc.). I am making the specific statement that traveling by plane to Europe is better than traveling by car to Europe from the United States. Isn't that objectively true since you cannot travel by car from the United States to Europe?
The thing is, once again, you are not fully defining neither the car nor the plane. That requires everyone to assume any undefined details are default, that is, common, normal, not special in any way. But people dont have the same idea of what a "default" car is, albeit they may be very close, and I dont think there is an international convention on what is a normal car. Off course, one's "default car and plane" would have to be way off course of society's standarts to make the car better than the plane at crossing the Atlantic.

What you call "subjective" is merely vague. And that has nothing to do with subjectivity or objectivity. It has to do with what it is you are saying.
It does. If it was possible to eliminate all vagueness from a statement, all statements could be objective. Then there is vagueness, the recipient must assume all the missing features, what will inevitably happen within his own standarts and limitations. That makes the statement subjective.

To go back to my other example, what objection have you to the statement that spoons are more useful than knives for eating soup (but knives are more useful than spoons for carving a roast. You think that is "subjective" too? Have you ever tries using a spoon to carve a roast?
Maybe its a tiny spoon and a curved knife. Maybe its a rusty knife and a sharp edged spoon.
