From my perspective the elephant in the room is something Tesla is unlikely to be able to compete against, particularly as more manufacturers come online with viable full range electric cars:  Constant innovation.<p>What I mean by that is car companies are geared-up and used to introducing new and seriously updated models every year or two.  They go through many iterations and designs, have hits and misses.  And they sell millions of cars per year in the process.<p>In another year or two the Model S will feel, well, dated and old.  I have to admit having had this very thought.  I&#x27;ve been considering purchasing one for the past year and was going to make a decision in January.  And I keep running in circles with multiple arguments in my head.<p>First there&#x27;s the &quot;this look is getting old&quot; argument.  Sorry, superficial, but, hey, that&#x27;s the way it works.  This this wasn&#x27;t a real-life criteria we all use to buy cars they would still look the way they did twenty years ago because nobody would care.<p>Then there&#x27;s the interior.  As others have pointed out, not the best. I&#x27;ll just leave it at that.<p>I find my self less interested in a car who&#x27;s outward and interior design is already several years old.<p>I am not interested in a Tesla because I am a fan boy.  I am not.  I would like an electric car because I have a nice solar infrastructure at home that I designed to be able to support two electric cars.  I also want to stop burning fossil fuel for transportation.  I am also very interested in lane-keeping or auto-pilot technologies while on a highway.  And, finally, it is a business decision based on facts:  I find myself driving quite a few miles per week and, if you do the math, going electric just makes sense.<p>Then there&#x27;s the question of battery technology.  I can&#x27;t help but think we are not very far from a shift in battery technology.  I, frankly, don&#x27;t want to find myself in two or three years with a US $90K Tesla sporting an outdated battery, outdated exterior and outdated interior and a tough resale landscape because Toyota, Nissan, BMW, Mercedes, Porsche, Ford, GM and even Yugo (raise your hand if you remember them) has a pure electric with 200+ mile range for $40K.<p>All car companies know how to make electrics.  It ain&#x27;t that difficult when compared to making IC cars.  In fact, if you already have a well-tuned infrastructure to build the rest of the car efficiently --which all other car companies have in droves-- building an electric car is actually simpler.<p>Tesla&#x27;s SUV?  Please.  It&#x27;s a joke.
