A driverless car (also called autonomous car or self-driving car, i.e. self-operating) is a vehicle that can perform certain tasks on its own, without the help of a human driver. The car uses sensors to analyze its environment, and doesn't need a human's help for certain tasks.[1] These tasks commoly include parking the car, driving while keeping the same lane on a highway or driving at a predefined speed. In public places, certain buses have been programmed to travel a given route. As of 2021, self-driving cars have been used in controlled envirnoments more and more. An example of this might be buses that transfer passengers between airport terminals.

Technology[change | change source]

Typical sensors used by a self-driving vehicle include lidar, digital cameras, GPS and IMU.[2][3]

High-definition maps can be used to accurately locate a self-driving car in a place, and to give information about parts of a road not seen by the car.[4]

Ethical issues[change | change source]

Even though it is technically possible to build cars that do certain things on their own, the question whether it should be done is different. Ethical questions include:

  • Is a machine able to judge a situation correctly? – Can it make a difference between a stroller with a child, and a stroller with a doll?
  • Is it acceptable to judge a situation by the expected death toll? (This has been formalized as the trolley problem.)
  • If it is acceptable to judge such a situation by the expected death toll, what are meaningful criteria? – should the age of those killed be taken into account?

Legal issues[change | change source]

Even though these vehicles can already do a lot on their own, the laws of most countries still require that a driver is present. In many cases, self-driving buses also need a special permit from the government.

If a motor vehicle produces an accident, there always is the question of who is responsible, to determine what damages need to be paid. This also applies to self-driving cars: A self-driving car is like a robot: Software is used for the driving. This software relies on a number of sensors to take decisions. Determining what went wrong in the case of an accident can be very difficult. This includes the question of who is legally responsible.
