Nearly a decade after its first announcement, Tesla's long-promised Roadster has been given yet another date with destiny: an October 1 unveiling, declared by Elon Musk on September 12. The sports car has come to embody a particular tension in the story of technological ambition — the gap between the vision proclaimed and the object delivered. Whether this date holds or dissolves into the pattern of delays that preceded it, the Roadster has already become something more than a vehicle: it is a referendum on whether grand promises, deferred long enough, can still be redeemed.
