After Theresa May passed the buck, her successor has put pragmatism first.
The sweeping introduction of driverless cars could see more vehicles on the road, driving longer distances. But smart planning could solve some of transit-associated environmental and social problems.
Self-driving vehicles that constantly roam the streets looking for passengers could overwhelm cities. But, if kept in check, these vehicles could be useful for improving urban transport.
Uber's London licence has been a political football for several years, but that's not really the point.
A whole range of social and technological changes could revolutionise how we travel in the coming decades.
Scenarios based on a survey of Adelaide commuters and analyses of traffic flows show it's possible the congestion could get worse in the transition to driverless vehicles.
Planes, trains and automobiles produced a step-change in the speed of travel – driverless and electric cars simply cannot deliver such radical improvements.
Could Knight Rider's KITT finally be on the horizon?
Self-driving cars may someday drop off their owners downtown and then leave to find free parking. What would that mean for cities of the future?
Academic experts on how the humble car could evolve to become an unlikely hero in the global fight against climate change.
When computers take the wheel, the emotive aspect of driving will change significantly.
Driverless cars will form a fast, efficient transport network, which will make car ownership redundant. But they could also spell the end of public transport.
The real ethical challenge of driverless cars is not deciding how they respond in emergencies – it's facing up to the failings of human drivers.
How will people respond once they realise they can rely on autonomous vehicles to stop whenever someone steps out in front of them? Human behaviour might stand in the way of the promised 'autopia'.
More manufactured cars are integrating assisted-driving technologies such as parking support and networked dashboards. But what should a consumer look for?
Autonomous mass transit vehicles like 'trackless trams' are a better bet than autonomous cars to give us people-friendly cities that capture the value created by infrastructure for the common good.
Using driverless cars to get from A to B in the future will mean more free time to do other activities – but will people really use it productively?
Can we really expect vehicles to make the moral decisions we can't?
An increase in the use of self-driving cars will change parking infrastructure in cities, and hopefully result in more colourful character neighbourhoods.
Beware of the blind use of artificial intelligence: used as a "magic wand", for example in an autonomous car, it presents risks.
