Driverless cars that can drive themselves without human input are being developed by major automakers and tech companies and some are expected to be available for purchase within the next few years. These autonomous vehicles could significantly impact transportation by improving safety, reducing traffic and lowering emissions while allowing people time for other activities while commuting. However, widespread adoption of driverless cars will likely disrupt the auto industry and related sectors by reducing private car ownership and insurance costs while changing energy demand. For driverless cars to be widely adopted, their benefits must be effectively marketed to consumers and issues like pricing and who is responsible in the event of an accident need to be addressed.
