As with any relatively new technology, there are risks to its use. Lynch says the first risk to consider is the privacy of individuals using connected vehicles, especially when it comes to location tracking. Another concern is the security of these systems. “Wireless communications opens a vehicle to the world,” he says. “If cybersecurity is not sufficiently robust, some bad people could access the vehicle and jeopardize its safety.”
According to Na Jiao, technology analyst at IDTechEx, self-driving technologies and connected and autonomous vehicles add another layer of vulnerability to cyberattacks. The concern is not only the vehicles themselves, but also the environment in which the vehicles operate. “The threats to autonomous cars can come through any system connected to the vehicle’s sensors, communication applications, processors, control systems, and external inputs from other cars, infrastructure, and mapping and GPS data systems,” she says.
Chris Greer, director of the NIST (National Institute of Standards and Technology) Smart Grid and Cyber-Physical Systems Program, says by contributing greater and more accurate awareness to vehicles, technology can indeed produce a roadway environment that exhibits better driver and driverless vehicle decisions, but there is also risk. “The key to managing risk is to ensure that we’re able to measure those risks reliably and accurately,” Greer says.
As long as the industry considers risks and continuously looks for ways to mitigate these risks, it’s safe to assume connectivity will revolutionize road safety. It may even shift the transportation paradigm.
