Self-driving cars will swarm our roads within the next couple of decades. They'll be cheaper, safer, more efficient.

Our grandchildren – heck, maybe even our children – will probably never learn to drive a car if they will live in an urban environment.

While it's fun to think about in a futurism sense, there will be little excitement where the real change happens. Autonomous vehicles will, by their nature, be boring. For the most part they'll have utilitarian looks. They'll be quiet and electric, they'll be slow and conservative drivers. They'll basically be a more personal version of public transport.
