Why U.S. Roads Are Far Deadlier Than Skies: The Case for Infrastructure-First Safety

Collision Rates: Skies vs. Roads

In the U.S., 11 car crashes occur every minute. By the time you finish reading this sentence, several vehicle collisions will have happened across the country—some likely fatal. In contrast, U.S. civilian aircraft experience about 1,200 crashes per year, with very few resulting in fatalities.

During peak times, 5,500 American planes are in the air simultaneously. Collisions are rare because airspace is engineered for safety. Planes must communicate with each other and ground control; no one can “opt out.” Our roads operate under a different system.

Why Roads Are More Dangerous

More than 280 million registered vehicles share U.S. streets with trucks, cyclists, and pedestrians—largely without systemic communication. This isn’t a failure of drivers or technology, but a failure of system design. The real problem is infrastructure, not vehicle safety.

Busy intersections highlight the uncertainty we accept as normal. Roadways are open systems with infinite variables: weather, pedestrians, distracted drivers, and aging infrastructure. Communication between vehicles is minimal, and infrastructure is largely silent. In that gap lies the potential for deadly collisions.

"When I was a child, I lost a close family member in a car crash. Sadly, that experience is not unique. Later in my career, that loss left me asking: why do we accept a level of loss on our streets that we would never tolerate in the skies?"

The Aerospace Lesson: Safety Through Shared Systems

The lesson from aerospace is clear: safety comes from mandatory communication and a shared system design, not from relying on each vehicle to figure it out independently. A shared safety layer must exist in both physical and digital infrastructure.

AI sensors and models need to monitor intersections and highways, understand interactions between vehicles, pedestrians, and other road users, and predict risk before collisions occur.

Why Aerospace Is Easier

In aerospace, safety is designed into the system from day one. During research at MIT—working on autonomous systems with NASA and the U.S. Navy—one principle was evident: no aircraft operates in isolation.

In both traditional air traffic control and newer drone management systems, safety isn’t an afterthought—it’s built on connectivity and constant information sharing. Aircraft continuously share their position and movement through standardized sensing and communication systems. Flight plans and operating rules allow ground systems to understand intent and predict future positions. This creates a shared, real-time picture of the airspace.

Humans and automated systems can spot conflicts early, coordinate decisions, and resolve risks long before paths intersect. That shared awareness is why near-misses in the air rarely turn into disasters.

Why Infrastructure-First Intelligence Works

If we can engineer safety for aircraft moving at hundreds of miles per hour, we can do the same for streets moving at 30 mph. Most traffic systems today react after something goes wrong. Predictive systems must intervene before conflict arises.
