A tragedy involving an Tesla S car was as much a warning as a sign of things to come, writes ARTHUR GOLDSTUCK, pointing to the Volvo XC90 as the current state of the automated art.
The very latest technology available in cars today is not the culmination of 130 years of vehicle evolution, but the beginning of the next era in that evolution. The most high-tech cars on the road today can be described as the ancestors of the next generation of self-driving vehicles.
It may strange to describe the very latest in terms we usually reserve for the distant past. However, this is the inescapable conclusion from a fatal car accident involving an automated Tesla S in May this year, and the features available in cutting edge cars right now.
Tesla’s own description of the accident tells us much about the current state of automated technology: “What we know is that the vehicle was on a divided highway with Autopilot engaged when a tractor trailer drove across the highway perpendicular to the Model S. Neither Autopilot nor the driver noticed the white side of the tractor trailer against a brightly lit sky, so the brake was not applied.”
The fact is that the Tesla S technology is more about auto-pilot than self-driving, meaning it is still a rudimentary form of self-driving. The motor industry understands this, and there have been few protests about the technology that “caused” the accident from that quarter. The media response, on the other hand, has been close to hysteria, with the normally sober Wall Street Journal declaring: “Scant Oversight of Self-Driving Technology”.
However, the fact that there is one single death from an auto-piloted vehicle can hardly be described as a setback for the evolution of self-driving cars, when autonomous vehicle technology is being researched, developed and evolved continually. The industry acknowledges that it is still at an early stage of its development.
None understand this better than Tesla itself, which warned: “When drivers activate Autopilot, the acknowledgment box explains, among other things, that Autopilot ‘is an assist feature that requires you to keep your hands on the steering wheel at all times,’ and that ‘you need to maintain control and responsibility for your vehicle’ while using it.”
One of the key consequences of the incident is that such warnings will become more heavily emphasised. Law enforcement will also probably step in, taking action against drivers who don’t have hands on wheels.
However, this misses a key issue.
We have evidence day after day, hour after hour, that human-driven cars are not safe. More than 35 000 people died in the USA last year as a result of being in accidents caused by human-driven cars. Not a mention of banning humans from driving cars.
We will see autopilot type functions increasingly built into cars. The technology will keep evolving and keep improving.
For example, right now, the Volvo XC90 car being sold in South Africa offers automated functions like Pilot Assist, which maintains a set speed or distance to the car in front, and Queue Assist, which controls acceleration, braking and steering while one is following the vehicle in front in slow-moving queues. One wouldn’t rely on ether of these to take over the driving, merely to assist with a smoother and safer ride.
Next year, Volvo will begin tests with select XC90 drivers using its IntelliSafe Autopilot technology, which is equivalent to Tesla’s Autopilot . The tests will at first be limited to Sweden, on roads with no pedestrians and clear separation between lanes.
Meanwhile, the current XC90 available in South Africa – the country’s Car of the Year for 2016 – is a showcase of the state of mainstream vehicle automation.
The City Safety collision avoidance system scans the road ahead for vehicles, pedestrians and cyclists. During testing by this writer, a momentary distraction that resulted in a suddenly reduced following distance activated an audible alarm that prevented a collision. Had there been no reaction, autobraking would have been applied to avoid or minimise impact.
A Lane Departure Warning System causes the steering wheel to vibrate if the vehicle beings to stray out of its lane without the indicator being activated. A Blind Spot Information System uses radar sensors to alert one to to traffic around the vehicle if one does plan to change lanes.
Driver Alert Control picks up drowsy or inattentive driving through comparing current driving with usual driving and prompts the driver to take a break.
A Road Sign Information system even warns, for example, when one ignores No Overtaking, speed limit reduction and No entry signs. The warnings appear in a heads-up display that is projected unobtrusively onto the windscreen in front of the driver.
All of these are futuristic experiences that will one day be standard in most vehicles, the way safety belts and airbags are today. Volvo’s target is that, by 2020, there will be no serious injuries or fatalities in a Volvo car. That, coincidentally, is also the target date for most manufacturers putting self-driving cars on the road.
Meanwhile, the technology from the future that we are using today comes with one overriding safety instruction: the driver still bears ultimate responsibility for safe driving.
