Beneath the motorway is something that keeps eating cars.  Usually, it's a pothole.  In "Gridlock" it's a plothole.  Oh, Russell T. Davies wants us to think it's the Macra, but we know better.  This week on the next to last stop on the Road Trip to the 50th Anniversary we attempt to fill in these plotholes and give you a look at the Tenth Doctor story "Gridlock".
