Hyundai Motor Group said it will spend $9.75 billion over the next five years on research and development into autonomous-car technology. The automaker says it plans to have partially autonomous cars ready by decade’s end, with fully driverless vehicles for sale in 15 years. “[A] great deal of research and rigorous product testing will need to be carried out to make the ‘self-driving car’ a reality,” said R&D Vice President Lim Tae-won.
