An autonomous shuttle bus put on display at CES in Las Vegas by German tech giant Bosch gives a glimpse at what the future of inner-city transport may look like. The spacious electric vehicle is a concept which features interactive screens for every passenger as well as high-tech camera systems used to ensure no belongings have been forgotten - and ensure no chewing gum is left stuck to the seats. Passengers will climb in and out of the vehicle using Bosch's own keyless entry system. It forms part of its growing Internet of Things initiative and shows off its market-leading sensors and hardware. The Sony Vision S car unveiled at CES this year was a similar idea, with Sony trying to muscle in on the autonomous car market by making its own hardware.
