GQ has an extensive profile on Travis Barker of Blink-182. This passage about the possibility of a Box Car Racer reunion sure is interesting:

I think we were both under the impression in the beginning that it was going to be a Blink album. Then it was like, no let’s do this cool little side project, but we won’t put an album out. Then the label heard it and wanted to put it out. Then there wasn’t going to be a tour, but they were like ah, you can do this tour. It just spiraled out of control. . . But I don’t know. [Mark’s] not in the band, so would it cause a lot of problems? Would it not? I have no idea. It’s something I can’t even wrap my head around just because I’m so proud of this album that we’re currently supporting. But I love Box Car. It was a cool album and cool sound.
