These words are a direct reference to Paul Walker and the sense of loss that Wiz Khalifa and so many others felt when he passed away. They are poignant words that speak to the pain of losing someone you love and the hope that one day, you will get to see them again.
Specifically this song is about saying goodbye to a loved one: a best friend, a parent, a sibling, a spouse, a family, someone or a group of people that we have spent time so much on, spent time caring for, spent time listening to and supporting each other. The worst time you want to say goodbye is when you are happy with them, but in the end it can happen. You always want to have that "one last ride" with them, but in the end all you can do is to wish them luck as they walk their own paths. And when you "see them again" all you can remember is the good times you have had with each other.
