Unfortunately, all of this mocking of Fisker's Karma is not going to amount to much if the guys at Tesla don't get their collective 5h!t together and start mass producing a marketable product.
It's market saturation that does more for an emerging technology/product to secure public acceptance and encourage desire for it, not to mention increasing demand for the improvement for said technology, as well as push sales demands.
Tesla is and has been at the cusp of the EV movement...it would be a shame if they let their edge dull due to personality conflicts/differing business ideologies...oh, wait a second....
Don't put too much stock in Tesla. Yep, they have the halo car right now...but I'd be Fisker has quite a few reservations. Besides, GM's Volt is not far off. It does not look as cool as the Karma, but it's a, well, version of it which should come out in enough volume to make a dent.
