Andrew Rose of, an insurance comparison site, tells insurers, “You need to be completely freaked out by the idea of autonomous cars—and completely relaxed.” He said in a phone interview that in 30 years, it’s likely most of the auto insurance business will be gone. Autonomous vehicles will wreck less over time, which means lower premiums will be required to cover losses, and therefore less auto insurance will be required. “Insurers can relax,” Rose said, “because it’s going to take time to get there.”
