An anonymous reader writes "In a lull between product launches Tesla intends to keep making improvements to the Model S according to Elon Musk. Tesla will automatically push software to the Model S fleet that will help the car learn the driver's habits and the navigation system will offer directions to avoid traffic jams. 'This year, Tesla is offering only the single model, the Model S that is EPA rated at up to 265 miles on a single charge, the most of any electric car. The company's next model won't come until next year, when the delayed Model X crossover goes on sale. Musk says the holdup has centered on making sure its signature design element, gullwing doors to make it easier to get in the rear, works properly and is leak-proof. "Getting the door right is extremely difficult," he says.'"
