From the VCR in 1970 to the Oculus Rift in 2013, the annual Consumer Electronics Show (CES) in Las Vegas has been at the forefront of tech trends.
Every year, around 170,000 people flock to see the new gadgets and concepts that have been dreamed up by over 4,000 exhibiting companies. Although CES originally focused on home appliances and computers, recent years have seen the increasing emergence of vehicles and vehicle tech in the show.
