When cars have the sensory systems around them, GPS intelligence, they're looking at the world not only in visual spectrum, but infrared, ultraviolet and everything else that's going on and they've got reaction times in microseconds. Not a tenth of a second. They're a hundred thousand times faster.

The paradigm I want to change is that, you can have a car that is beautiful, manufacturable, affordable, safe, fast, and oh, by the way, does 100 mpg, or its energy equivalent. Why wouldn't you?

What is grit? Grit is refusing to give up. It's persistence. It's making your own luck.
