It seems I am the only one bothered by putting useless junk into the universe. I don't even know how it's possible that they were allowed to litter space just for the sake of it. Like there's not enough human garbage rotating in orbit. Couldn't they send a small probe or something more useful than a car ? Also human space travel is just the answer to none of our current and urgent earthly problems. I don't get why people are so unreasonably hyped about it.
