That someone would die in a ‘self-driving' car was as inevitable as the furore that has followed. Yet, as tragic as the death of Tesla owner Joshua Brown is, there remains no question in my mind that autonomous cars are a part of all our futures.

The reasons are boiled down easily: they will be safer, they will be less polluting and they will reduce congestion. All three arguments are too appealing to governments and lawmakers to ignore, no matter how difficult the path is to getting there.

That path is well laid out now. Tesla is at the forefront of the movement, but it's worth stressing that Autopilot has always been billed as a driver aid, not a fully autonomous technology that allows you to surrender the need to be in charge of your vehicle. Almost every car maker is on a path to having a car on sale that allows you to take your hands off the steering wheel for brief periods within the next three years, your feet off the pedals as well in the next five to ten years and to switch your brain off entirely and let the car do the work in the next 10-15 years.
