Improving battery technology is the main challenge for electric vehicles to succeed. As always Elon Musk and Tesla are at the front line of innovative technology. Keep on innovating and you will make it. Go Tesla!
BTW: Hi Elon Musk, when do you start publishing on STEEMIT?
There is no limit in human potential of ingenuity, if we stop saying "it is impossible" and start saying "how can I achieve this". People like Musk are real heroes of humanity.
