    Of all my dreams, my least favorite is the one where I'm in a car. It always begins with me driving, but eventually I realize that for some reason I'm sitting in the back seat. I can’t keep the car under control, rushing toward the roadside until, screaming, I wake up.

This is like the passenger experience in Waymo's self-driving cars. You sit in the back seat of a vehicle and watch as the wheel turns itself above an entirely empty driving seat.

''We made you live your nightmare, '' a Waymo staff member joked after I exited one of the company's fully self-driving car, following a quick drive inside its secret testing site. Waymo, a self-driving car company, arranged these rides for 40 journalists at this site.

There were also some demonstrations(演示). We watched as a Waymo car was cut off by a speeding vehicle. Then the employees created a situation in which a pile of moving boxes fell into the street just as another car passed in the opposite direction. Throughout the day, the cars performed impressively, driving with the level of care you might take if you had a wedding cake in the back seat.

During these demonstrations, Waymo gave information about what it was planning to do with these vehicles. The company has laid out four ways that its technology could be made available to the public. But Waymo's CEO, John Krafcik, wouldn’t show which of these was likely to come to market first, or on what kind of timeline.

I can't help but admire that Waymo is succeeding in developing this technology. There are countless possibilities at play on the road. The task of programming software to react to all those situations is unimaginably complex. What a great breakthrough!
