[Destiny] Why is there a lot of 20th-21st century junk in the cosmodrome?

So, if I've got my timeline right. Humanity is just chilling, doing it's thing. Then traveller appears, gives everyone superpowers and shit. Humanity starts becoming über advanced under traveller's guidance and protection, has a golden age, spreads across the stars, colonised planets, builds super cool space ships, etc. Then, darkness comes along, begins to pwn traveller, humanity collapses and retreats to the tower (last city).

Therefore, we should be looking at the wreckage of a super-advanced humanity with sleek spaceships and flying cars, etc. So why do a lot of the burnt out cars and planes in Russia look more late 1990s than 2290s? Was the traveller anti-Russian and didn't let them advance as much?

We can only presume it was used as an Aircraft Graveyard during the Golden Age. As for cars, flying cars aren't really practical in large numbers.. you have an issue of not clearly defined lanes etc. The only advances in cars would probably have been cleaner and more efficient engines plus a few other safety features.
