So I repeated the experiment. I went 300 miles out of Delhi into a really remote village where the chances of a passing software development engineer was very little. (Laughter) I repeated the experiment there.
So as a result, the energy usage is very low, and it has the most advanced battery pack, and that's what gives it the range that's competitive, so you can actually have on the order of a 250-mile range.
So I got in my car, and I drove three hours north along the coast, and the roads grew emptier and narrower, and then I turned onto an even narrower path, barely paved, that snaked for two miles up to the top of a mountain.
Night had fallen, and I went out under this great overturned saltshaker of stars, and I could see the tail lights of cars disappearing around the headlands 12 miles to the south.

Gray whales off America migrate 16, 000 kilometers between productive feeding areas and less productive calving, or birthing, areas and back every year.
That's important, because although they are able to hear chainsaw noises up to a kilometer in the distance, allowing them to cover about three square kilometers, if someone were to take them, it would make the area unprotected.
