Self-driving cars

Major advances in computing power and software have made self-driving cars not just a pipedream. Computer vision algorithms in cars can now identify objects, such as pedestrians, stop lights or lane markings, with impressive accuracy. Cameras and radars collect tons of data, which cutting-edge machines can parse to help plan a safe course to your destination.

Recently, Drive.ai -- a Silicon Valley-based startup building self-driving car software -- said it will offer free rides to passengers in Frisco, Texas, between offices and retail stores. Waymo, the self-driving arm of Google's parent company, has a similar program and will launch a paid service in the Phoenix area by year's end.

But plenty of hurdles remain. Most Americans are still afraid to ride in a self-driving vehicle. In March, self-driving Uber struck and killed a pedestrian in Tempe, Arizona, raising skepticism about the industry.

Although it's hard to tell which of these transportation concepts will succeed, don't count on your commute to stay the same.
