Space opera, but 99% of it takes place around the Earth and the Moon

You can get a space car and fly through space. But you're not visiting other solar systems with FTL warp drive in your little space car. Even going to Mars would take months/years. It's a 3 day (or less) drive to the Moon, though, and there's lots of fun stuff to do on the Moon. What's more, there are also plenty of orbital cities built around the Earth and the Moon, and you can fly to those. Also, astronomy from Earth's surface is 100% fucked by said orbital cities, so you'll have to fly out really far with your space car and a telescope packed in the trunk, to get a good view of the Milky Way.
