And much more.
It takes a long time to plot a position for a new satellite because of the amount of space junk currently in orbit.

When a satellite (or a car) is way beyond Earth orbit there is indeed a vast amount of space with very few, and easily tracked, man-made objects around. So the Tesla isn't going to be an issue, especially since it is not in a highly targeted and valuable orbit.
In Earth orbit though it is getting very cluttered and junk needs to be taken into account. Not so much for plotting a position for a new satellite but for the launch of a new satellite where you are cutting (albeit briefly) through the orbital paths of a lot of working satellites and debris.
