Why I'm skeptical about Toyota's approach to self-driving cars - Ars Technica

Toyota hopes to eventually license its Guardian technology to other automakers.

  As most of the car industry have scrambled to develop fully driverless car technology over the last few years, Toyota has taken a pointedly contrarian tack.

  On the other track, dubbed "Guardian," Toyota is working on more sophisticated driver-assistance products—products that can intervene when a driver makes a potentially deadly mistake.

  In one 2017 video, for example, Toyota demonstrates a prototype Guardian vehicle automatically changing lanes on a freeway (actually a private test track) to avoid hitting a wheelbarrow that's been left in the middle of the road.

  Toyota will probably discover some scenarios where a car can intervene with minimal danger of causing a crash or confusing the driver.

  For example, Pratt showed an example in which a car suddenly emerges a few feet onto the roadway from between parked cars: It's not crazy to think that, in this scenario, the Guardian system would be able to quickly verify that there are no obstacles to the vehicle's left and then swerve a few feet in that direction—just enough to avoid a collision.
