Passenger Seat

I'm not saying this is the correct interpretation or anything but this is what I imagine when I listen to this song. A guy is driving his girlfriend home late at night and she's tired. She's been wanting to ask him something and now since they're alone it's the perfect time. She wonders out loud on the lines: "I strain my eyes and try To tell the difference between shooting stars and satellites." I think this is metaphorical and the shooting stars represents love while the satellites represent society. She's wondering whether anyone or anything will get in the way of their love when she asks "do they collide?" He answers her by smiling, assuring her nothing will ever get in the way of them. She feels more comfortable and realizes that the rest of society really doesn't matter and won't ever change their love. He then continues to tell her "when you feel embarrassed then I'll be your pride, when you need directions then I'll be the guide, for all time, for all time." He tells her that he will always be there for her and love her, forever.
