Character-wise, Shattered Glass Tracks is probably the least inventive of the Shattered Glass characters. He’s basically the exact same as regular-universe Tracks; remarkably vain and conceited.
However, depiction-wise, he is a wonderful head nod to the history and even pre-history of Transformers. Upon first seeing him, a lot of fans cried, “Road Rage!” from the exclusive red version of Tracks put out by the Takara affiliate store eHOBBY as the original G1 character Road Rage. In truth, Road Rage — who is incidentally a female Transformer — and Shattered Glass Tracks share a common homage, that of the original pre-Transformers Diaclone Corvette toy from which G1 Tracks’ toy came.
For reasons unknown, Hasbro eventually chose to put out G1 Tracks in a blue colour scheme, but the red paintjob could still be seen on the Transformers 1985 box art.
Though I much prefer him as Shattered Glass Tracks, it is nice that those that would like a Generations-style Road Rage can grab some Reprolabels and turn him into her.
The red detailing really works well with this mold’s alt mode too, perhaps even better than the blue deco.
Of course, flying car “attack alt mode” is there too.
So yeah, there’s not really much else to say about Shattered Glass Tracks. A pretty lackluster attempt at the evil incarnation of an established character, but a pretty spectacular implementation of Transformers pre-history resulting in a great toy.
