The mystery box sits inside an all-white room in an office building in San Francisco. It’s a large, wooden crate with no features other than the word “ZOOX” in big, black block letters and a sturdy-looking padlock. For about $100 million, you can get a key and have a look inside.
 Few have had the pleasure. What they saw is a black, carlike robot about the size and shape of a Mini Cooper. Or actually, like the rear halves of two Mini Coopers welded together. The interior has no steering wheel or dashboard, just an open space with two bench seats facing each other. The whole mock-up looks like someone could punch a hole through it. But because you’ve just invested $100 million in the thing, you’ve earned the right to have a seat and enjoy a simulated city tour while you pray that this vision of a driverless future will come to pass.
 Of the many self-driving car hopefuls, Zoox Inc. may be the most daring. The company’s robot taxi could be amazing or terrible. It might change the world—not in the contemporary Silicon Valley sense, but in a meaningful sense—or it might be an epic flop. At this point, it’s hard to tell how much of the sales pitch is real. Luckily for the company’s founders, there have been plenty of rich people excited to, as Hunter S. Thompson once put it, buy the ticket and take the ride.
