The US car giant, Ford, has jumped into the driver’s seat (or not, as it turns out) in the race to produce the first mass-market driverless car. Last week it announced that it will build a completely self-driving car by 2021 and that the cars will be specially designed for commercial services such as taxiing and ride-sharing. The move puts Ford – which has also announced a number of investments in technology companies – in direct competition with the likes of Google and Apple, as well as car manufacturers such as BMW.
