- According to wikipedia, the launch mass of the Falcon Heavy is about 26 tons for a geostationnary launch, which is quite a lot and definitely enough for ISS like launches. I guess either the launch mass is way lower for leaving earth's orbit, or either they just wanted to prove they could ship in something of significant mass without having to pay for all the required fuel. - For Roadster's orbit, most of the time it will be fine, however some have predicted that it will end up crashing on Venus in a few million years [0]. And that makes me wonder whether the Roadster has been properly disinfected (I very much doubt so). Also, for one of your original questions, the car is completely alone on its orbit, not enclosed in anything. From what I understand [1] the last booster separated itself from the car before burning during re-entry. You can see clear and beautiful pictures of the car around Earth [2]. Edit : I was wrong, the car is still attached to the last booster.
