When survey respondents were asked to assign a ranking to six possible roadblocks to the mass adoption of driverless cars, legal liability, policymakers and consumer acceptance were ranked as the biggest obstacles, while cost, infrastructure, and technology were viewed as the smaller challenges.
"Anytime you have a technology that has the potential to fundamentally change our daily lives, laws and policies need to be established to ensure the technology is going to be used properly and benefit humanity. This is especially true with intelligent vehicles," stated Yaobin Chen, IEEE senior member and professor and chair of electrical and computer engineering at Purdue School of Engineering and Technology. "Once the foundation elements, like legal liability and policy, are in place, the technology and infrastructure will be there, so intelligent vehicles will become more widely accepted."
As more autonomous features are being incorporated into cars, it will enable them to be manufactured without some of the equipment that is commonplace today. When asked to specify the year in which specific equipment will be removed from mass-produced cars, the majority of respondents believe rear view mirrors, horns, and emergency brakes will be removed by 2030 and steering wheels, and gas/Brake pedals will follow by 2035. In addition, more than 75 per cent of respondents also indicated that all 50 US states would pass legislation permitting use of driverless vehicles within this time period.
"We've seen incredible growth in the driverless vehicle industry over the past few years, both in technological advancement and manufacturer acceptance, that has dramatically affected the consumer adoption timetable," stated IEEE Fellow Alberto Broggi, professor of computer engineering at the University of Parma in Italy and founder of
Advances in technology will be the most instrumental in the continued development of driverless vehicles, with more than half (56 per cent) of respondents believing that sensor technology is most essential, followed by software (48 per cent), advanced driver assistance systems (47 per cent) and GPS (31 per cent).
"A driverless car needs a constant stream of information of the road and its environment to make calculated decisions, which are referred to as perception. Sensors are one of the most important and trusted technologies for advancing perception scenarios," stated Christoph Stiller, IEEE member and professor at Karlsruhe Institute of Technology, Germany. "Sensors are small, non-intrusive and offer reliable data. Also, sensor technology is relatively cheap and will be influential in creating affordable driverless vehicles."
Along with sensors, creating digital maps of the road is a necessary function for allowing autonomous vehicles to travel safely on the roads. When asked to predict how long it will be before a complete digital map of the world will exist, nearly three quarters (74 per cent) of respondents indicated these maps will be available within the next 15 years.
While autonomous cars will prove to be beneficial around the global, the majority of experts (54 per cent) believed that North America would most benefit from driverless vehicles, with Europe second (28 per cent) and Asia (17 per cent) rounding out the top three.
The survey was given to attendees at the IEEE Intelligent Vehicle Symposium in June and distributed via email to members of IEEE's Intelligent Transportation Systems Society. Industry experience among participating experts of the survey ranged from university students to those with more than 20 years of experience. The analysis of the results revealed consistency through every experience level, indicating that time spent in the field was not a factor in providing insight into the future of the driverless vehicle industry.
