The automotive and tech industries are confident in the future of autonomous vehicles, a new study shows.

Many automakers and suppliers say they believe many cars will be highly functional without driver intervention by 2020. The insurance industry, however, is less convinced of the driverless car revolution, according to a study released Wednesday by audit, tax and advisory firm KPMG LLP.

The survey, "Automobile Insurance in the Era of Autonomous Vehicles," asked senior executives representing $85 billion of the personal and commercial auto insurance industry about the impact of autonomous cars on their business.

The results are a bit startling, given the potential pitfall driverless cars could have on insurance and premiums.

Of those surveyed, 84 percent don’t expect autonomous vehicles to significantly impact the insurance business until 2025.

Experts believe significant portions of driving will be automated by 2020, including where drivers don’t drive in traffic jams, on freeways and in other highly predictable situations.

Fully driverless cars are expected to reach 11.8 million units in the U.S. in 2035, according to Egil Juliussen, an analyst at IHS Automotive. And by 2050, he expects almost all cars to be self-driving.

At issue is whether the insurance executives are educated on the implementation and effects of autonomous cars on society. Only 29 percent of those surveyed said they felt knowledgeable about autonomous vehicles and even fewer, 10 percent, had developed a strategic plan to handle the shift likely in their business plan.

“The disruption of autonomous vehicles to the entire automotive ecosystem will be profound, and the change will happen faster than most in the insurance industry think,” Jerry Albright, principal in KPMG’s actuarial and insurance risk practice, said in a statement. “To remain relevant in the future, insurers must evaluate their exposure and make necessary adjustments to their business models, corporate strategy and operations.”

The insurance executives, while skeptical of the technology’s impact, say they do believe the industry will change over the next 10 years.

Of note, 39 percent of respondents said they believe new providers will crop up to take on the driverless horde. Fifty eight percent of respondents cited automakers as potential new insurance providers.
