- This could have something to do with the "torque sleep" mode Musk promised for Tesla's dual-motor models that boosts efficiency by intermittently tweaking power output to each motor while coasting. However, Musk says this over-the-air update affects all Model S sedans, so that's probably not it, and just managing power output might not be "the end" of range anxiety.
- Then there's the battery swap possibility, which hasn't rolled out to anyone beyond one station accessible to maybe a few dozen (at the most) hand-picked Tesla owners (likely employees). That's more of a hardware thing than a software thing, so maybe there's more to read between the lines.
- Finally, Musk and his engineers have figure out how to wirelessly send power to the Model S using a combination of satellites, mirrors, and thousands of solar-powered lasers that charge the batteries using magic crystals and unicorn tears while the cars are in motion.
