With the future of automotive transport fast becoming a driverless utopia, there are lots of hurdles to cross to ensure the safety of all road users is at the forefront of all technological advances, such as artificial intelligence (AI) driven vehicles.
A race between two driverless electric cars recently took place in Buenos Aires. Both cars were created by Roborace, a company looking to set up regular races between driverless cars for entertainment purposes but also to better understand and develop driverless technology. Straight away I can see benefits to this, especially from a health and safety perspective. No driver equals no injury, should anything go awry on the track.
Unfortunately for the Roborace’s two Devbot cars, a crash did occur. One of the cars attempted to take a corner too fast, clipped it, causing damage to the exterior of the car and ultimately causing it to crash out. As this race (or experiment) took place prior to the Buenos Aires Formula E race, there were spectators and race staff around the course which may have resulted in injury.
However, in terms of risk management, this risk of injury was successfully mitigated through several control measures, such as a speed limiter being activated on the cars, with one car topping out at 116 mph, and crash barriers being in place. Alongside this, other control measures could be put in place, such as emergency braking systems and safe distances kept from the track.
Both cars were controlled by AI software – computer programs designed to drive the car, observe and monitor the local environment and, ultimately, ensure a safe drive. Devbot 2, however, did not manage this and crashed whilst travelling at high speed. Computers aren’t perfect, which I’m sure we all appreciate at some level.
Now, despite the car crashing and not finishing the race, as it is just a computer program in control there were no human injuries to consider or deal with. Specialists can review what happened prior to the crash, kind of like a dashboard cam, although with much greater detail. Going forward, all that needs to be done is get a new chassis up and running and to redownload the AI into the car, hopefully having learned from its mistakes the first time around. After all, the whole point is for these cars to learn and become better.
The worrisome thing for me is the fact that the cars are AI controlled. I have nothing against AI making life easier, my main concern is that each AI-controlled vehicle will, in essence, be different from the next. In a real-life on road situation, how can a driver in control of a car predict what a driverless car is going to do if they are always learning and vice versa? One car may do something completely different to another when put into similar situations, the same way human drivers are prone to reacting differently. Risk assessing against unpredictability is a tricky situation to be in.
In addition, any company investing in driverless technology will also have to consider asking themselves whether any risk scores they attain should be considered ALARP. Over time, through risk mitigation, the risk of death due to dangerous driving will reduce as a chaotic element (humans!!) will be removed from the equation. I guess the introduction of autonomous cars will be a slow culture shift for the world to contend with. Global Change Management would be great here although, in reality, impossible to manage. However, with Dubai now having approval for single occupant drones, perhaps lessons learned there will cascade down to the road level.
Regarding risk management, ‘expect the unexpected’ is a good mantra to follow. Another one I like is, ‘if it could go wrong, it will’. If we do begin to assess against the unexpected occurring, then I am sure some level of successful mitigation will be in place for driverless automotive transport. A recent report I read on the Deepwater Horizon disaster summed it up nicely when it stated these days, with risk, most organisations/individuals are focused on the possibility of successfully mitigating an issue whereas more organisations/individuals should be focusing on the possibility of failure instead.
But then, should the principle of ALARP start creeping in, a business has to make the call as to when they stop researching mitigating measures or controls. If a risk cannot be further mitigated against due to it being a financial sinkhole or requiring too many resources that far outstrip the risk appetite of the company in charge, then issues could arise.
I am sure no company in charge of driverless technology would ever mark a potential risk that may impact human lives as ALARP. The more tests that are done, through the slow introduction and culture shift discussed previously, the better the technology becomes until one day – I am pretty sure – the majority of journeys will be completely undertaken by faithful AI companions. After all, wouldn’t it be nice after a day at work to simply ask your car to take you home?
