The Hidden Dangers of Self-Driving Seats: A New Era of Crash Testing Requires a Fresh Look at Safety Standards

Self-driving cars are revolutionizing the way we think about transportation, but they also bring new challenges for safety regulators and car manufacturers. One issue that has been quietly lurking in the background is the impact of reclined seats on crash testing. With autonomous vehicles becoming increasingly common, governments must reassess what happens when passengers aren’t sitting upright.

According to federal safety data, over 40 people killed in traffic crashes in the past decade were identified as being seated with their back reclined. However, this number may be an undercount, as it can be difficult for responders to determine exactly how victims were sitting before a crash. The lack of field data on reclined occupants has hindered regulators’ ability to develop new safety standards.

The emergence of self-driving cars like Tesla’s Cybercab and Zoox’s bidirectional vehicle presents an opportunity for governments to revisit outdated regulations. As Becky Mueller, a senior research engineer at the Insurance Institute for Highway Safety, notes: “Autonomous vehicles are finally convincing regulators to open up some archaic rules and make modifications that can help modernize regulations for other vehicles too.”

Advanced crash-test dummies designed to mimic the types of seatbelts and seating conditions found in autonomous vehicles may be one solution. Humanetics, the world’s largest manufacturer of crash dummies, is working on such a project. Their THOR (Test device for Human Occupant Restraint) dummies come in different sizes and can be tested with various types of seatbelts.

Regulators will need to navigate a lengthy process to propose, fund, and complete new studies, followed by public comment periods. This process won’t happen overnight, but it’s essential that regulators take action to address the safety concerns associated with reclined seats in autonomous vehicles. As Mueller says: “It’s a good time to make sweeping changes.”

The widespread adoption of self-driving cars on the horizon demands attention be given to this issue. Companies like Tesla and Zoox are pushing the boundaries of what’s possible with autonomous vehicles, but they’re doing so without fully addressing the safety concerns that come with them.

The Current Safety Standards Are Outdated

Current safety standards assume occupants are seated upright, which is no longer a given in the era of autonomous vehicles. Airbags and seatbelts are designed to work under these assumptions, but when passengers recline or sit sideways, the consequences can be catastrophic. Seatbelts tighten around soft body parts instead of hard bony areas, leading to internal bleeding, lower spine and pelvis injuries, or damage to internal organs.

The Development of Advanced Crash-Test Dummies

The development of advanced crash-test dummies is a promising step forward in addressing this issue. Companies like Humanetics are working on THOR dummies that can be tested with various types of seatbelts and seating conditions. These dummies will allow regulators to better understand the risks associated with reclined seats and develop new safety standards.

The Path Forward

Changing safety standards won’t happen quickly, but it’s essential that regulators take action to ensure the safety of passengers in autonomous vehicles. The process involves proposing, funding, and completing new studies, followed by public comment periods. It’s a daunting task, but one that’s long overdue.

The future of self-driving cars depends on addressing the safety concerns that come with them. By developing new safety standards and crash-test dummies, we can ensure that passengers are protected from the devastating consequences of traffic crashes. The clock is ticking for regulators to take action on this issue. With widespread adoption just around the corner, it’s time to get serious about safety standards. We owe it to ourselves and our loved ones to ensure that we’re protected from the hidden dangers of self-driving seats.
