Rubber Physics

Just finished skimming "Traffic.  Why We Drive the Way We Do" by Tom Vanderbilt.  I was hoping that it would solve a technical problem in one of my short stories, but it didn't.  Or at least the parts I went through didn't.

So now I'm left to my own devices about what to do with the story, which is about traffic, and which (according to two engineers at the Wordos critique table) has a fundamental flaw in its understanding of how traffic works (they weren't quite pounding the table and chanting "Ringworld isn't stable!" but it was close).   

Maybe I can have one of my North American circa 2009 characters invoke "graviton waves."
