Watch what Nissan is doing. LEAF emerging as full electric vehicle and mid-size segment leader for the mass. And in 2014 Nissan launching full electric Infiniti to enter in luxury segment where Tesla is playing. TSLA will suffer ..... this stock over-price.
It will HELP Tesla by increasing the demand for more chargers. Is Nissan planning a car better able to cross country? I LOVE the Nissan Ecar racing program. They are going to Le Mans next year with an Ecar. Tesla NEEDS REAL competition!
Range of the Leaf is getting more useful but it's still a totally different beast. Go check out a Leaf it's a very low end car as far as the interior etc. It does it's thing and might sell better going forward but no one out there is saying "I was going to buy a Tesla Model S but look at the range improvement in the Leaf, I'll buy the Leaf." I'm not familiar with the Infinity right now but I'm sure that won't be cheap.
