Self-Driving Cars

A self-driving car is capable of sensing its environment and navigating without human input. To accomplish this task, each vehicle is usually outfitted with a GPS unit, an inertial navigation system, and a range of sensors including laser rangefinders, radar, and video. The vehicle uses positional information from the GPS and inertial navigation system to localize itself and sensor data to refine its position estimate as well as to build a three-dimensional image of its environment.

Describe technology and how it works.

· The software can recognize objects, people, cars, road marking, signs and traffic lights, obeying the rules of the road and allowing for numerous random hazards, including cyclists.

· The self-driving car detects road works and safely navigates around them.

· Powered by an electric motor with around a 100 mile range, the car uses a mixture of sensors and software to locate itself in the real world combined with highly exact digital maps.

Describe the safety concerns of this technology from multiple points of view


  • The car itself is limited to 25 mph.
  • Front of the car is also made of a foam bumper and a flexible windscreen that’s is designed to absorb energy from an impact with a person’s body.
  • Emergency stop button that passenger can hit at any point.

Your thoughts on the life of the technology (how long will it last- when will it become obsolete)?

  • My thoughts are that this can help people that cannot see or walk.
  • Will it become obsolete I don’t think so because it will sell a lot for the people who are in need of it.
  • I think it will last long because people are in need of it.

A First Drive

What is the cost of the technology? (Dollar amount, privacy, social cost, psychological, etc.)

  • Creating a 360-degree view of the vehicle’s environment requires a combination of sensors and may cost more than consumers are willing to pay.
  • Light Detection and Ranging (LIDAR)-based systems provide 360-degree imaging but are complex, expensive, and not yet ready for the market.
  • The LIDAR system used in the Google car, for example, cost $70,000.
