By saying it failed just because it is going 0-60 1 second slower than first projected is just the hater in you
Sure it does not have the all around practicality of a regular car, and of course no where near the practicality of a GT like a Corvette. But with a ~200 mile range, good looks in a package that will be fun to drive, it sure makes for a fun car to commute in.
All in all, this is a very expensive toy.
