Now of course your comment touches on the future of electric vehicles, keeping in mind the electronic companies hiding in the background behind Tesla Motors testing the waters based upon Tesla Motors Experience.
Forget Chevy, Ford, GMH, the new motor builders or road appliance manufacturers will be the electronics companies. Some mergers, some acquisitions and of course Korea's unique vertical integration of manufacturers mean they are already there.
So say Sony and Panasonic motors, with a largely electronic vehicle, running FOSS but with content management as an extension to the Big Screen Computer, the Tablet remote, the mobile phone and of course the ultimate mobile (also all the other home appliances), the car or more a utility vehicle with greater emphasis on function, the all electric compact SUV, in the city or out in the country on a picnic and still providing access to shared content and helping to create new content.
That better battery is drawing a huge amount of focus, lighter with greater capacity and low manufacturing cost, the current technological holy grail in so many areas, cars, mobile devices, home energy generation and storage. With that level of focus the better battery is likely not that far off and it puts current automotive manufacturers under serious threat as well as of course the fossil fuelers.
