Two developments that will have an impact are driverless taxis and mobility apps for smartphones. Google has attracted a lot of attention with its self-driving car, but many other companies are just as advanced in their testing, with many of the latest road models already offering autonomous features such as adaptive cruise control and lane changing. While there are technical and legislative barriers to overcome, fully driverless cars are likely to be on the road in the next 10-15 years. Initially they will be expensive to own; more immediately, driverless taxis may be cheaper than minicabs, and more comfortable and sociable as seats can face each other, with no need for a driver’s seat.
