Frankly, the likes of Honda and Toyota are probably laughing at tesla. Once their ducks are all lined up their size will allow them to produce electric cars at an insane scale. Shortsellers bet on this happening sooner than later and have so far lost that bet. But that doesn't mean it cannot happen tomorrow. Telsa is still on a knife's edge, will be for a decade or more. Tesla knows this an so is trying to leverage its battery know-how into other fields, a hedge against a decent honda electric hitting the US market.
