Self-driving cars have the potential to make travelling easier and safer than ever. Getting around an unfamiliar city could be as simple as opening an app and hailing an autonomous car. Technically speaking, self-driving cars are already on the road, thanks to a number of brands - but they're not legally allowed to fully drive themselves yet on public roads, and may not be for a while yet.

There is a long list of companies working on self-driving vehicles, from traditional car manufacturers such as BMW, Audi and Volkswagen, to tech companies such as Uber, Tesla and Google. The most notable company in this field is Tesla, which is constantly rolling out software and hardware updates for its cars to improve their autonomous capabilities little by little. Its Autopilot system can already drive a car better than a human, Tesla says, though right now you're only legally allowed to use it to help you stay in lanes on a motorway, change lanes when needed, and adjust the car's speed based on the traffic around it.
