CES 2017: emotional cars, sick bags and a 'listening' hairbrush

If this year's CES continues to predict future tech trends, then we can soon expect to have emotional relationships with our cars, virtual reality devices so realistic you need a sick bag, and products so pricey most people won't be able to afford them. One of the main themes this year at the premier electronics convention, which is held annually in Vegas, is that in the future everything will have a relationship with everything. The Faraday Future FF 91, a family-sized electric vehicle with the acceleration of a Formula 1 car and a "brain" that will apparently be capable of learning from its driver, was unveiled at a media event on Tuesday, before Toyota and Honda took the concept of an intelligent car even further. Toyota showed off its "Concept-i" concept car, which it described as: "More than a machine. It will become our friend".
