January 1 2017 promises to be an interesting day on the roads of Gothenburg, Sweden. It will mark the start of a two-year test scheme involving 100 fully autonomous – or self-driving – Volvos.

On that day, city locals caught up in the rush hour grind may very well cause a disproportionate number of traffic incidents by being distracted by the amazing self-driving cars they’re running alongside. But Volvo, being Volvo, will probably have thought of that. The long-term plan is for autonomous cars to make roads in Sweden – and around the world – significantly safer places to be by eliminating human error.

The test scheme, which has been created by Volvo but is supported by city authorities, road network stake-holders and the Swedish government, will be the first in the world to put autonomous cars into the hands of ordinary drivers, in amongst normal daily traffic, in significant numbers. It’s a bit of a landmark in the development story of the modern car. And Volvo gave me an idea what life will be like for the ‘drivers’ of those pioneering test cars yesterday, after a ride in one of its ‘driverless’ prototypes.

An S60 with one or two extra little boxes taped to the bodywork, this early development car primarily used only the hardware already fitted as part of Volvo’s existing active safety systems, together with some updated control software, for eyes. The finished test cars will be more advanced – although exactly how much more will depend on how much Volvo’s market research suggests that people are willing to pay for autonomous technology.

And yet, even now, Volvo’s concept works. The car drove itself for about 15 miles, down a fairly quiet stretch of Gothenburg’s answer to London’s North Circular. It braked when cars cut in ahead. It kept in its lane – although tended to weave a little bit within that lane when negotiating bends. But at all times, it seemed failsafe: ready with a warning to the driver when it needs you to intervene, or it suspects you may be in need of a wake-up call.

The latter bit’s particularly important. Volvo’s vision for the autonomous car is that it can work largely unsupervised by the driver – so that you can read or work, leaving the car to take the strain. But it wants you to remain alert and ready to take control – something the law is certain to mandate anyway. So, as well as having cameras looking forwards down the road ahead and behind, the driverless Volvo has one in the dashboard, looking right at you. Clever software studies your face and checks how often you’re looking at the road ahead. If you don't look up for a while, or even nod off, the car will wake you up.

I was unnerved by the idea of a platoon of self-driving, big-brother-governed cars to begin with, but detailed acquaintance with how it all might work, and the legal framework imagined around it, reassured me. Being given the freedom to work, talk, read or just rest on busy stretches of the commuter network sounds like a liberating idea.

It’ll be decades before autonomous cars can handle the entirety of your journey – not least because legislation and the insurance industry will need to be ready first. As things stand, the 1968 Vienna Convention insists that a driver is “at all times in control of a vehicle and fully responsible for its behaviour in traffic,” – so that’ll need an update just for starters. But the terms of that convention are already interpreted differently around the world, and special conditions and exceptions have been made in places like Germany and California, to allow the likes of Daimler and Google to experiment with autonomous prototypes.

I commute more than 200 miles most days of the working week, and I’d be willing to pay a decent premium for a car that could take over for a chunk of that journey, giving me time to catch up on other things. 

I’ll consider it a success when I can write something like this blog at 70mph on the UK motorway network, before posting it for you to read via in-car connectivity technology, and then taking over the reigns for the last interesting twenty miles of my trip home. That, says Volvo, could be possible within the next decade: well within it, in fact. Let’s hope they’re right.
