Sam Schmidt is riding again in Indianapolis

INDIANAPOLIS (AP) — Sam Schmidt is on the track again in Indianapolis.

The once-popular IndyCar driver was left a quadriplegic in a racing accident in 2000. On Sunday, he took to the famed oval in a 2014 Corvette C7 Stingray adapted to his needs.

He completed a modified four-lap run in a car bolstered by infrared sensors and other cutting-edge technology that allowed him to steer, brake and turn.

“The first time I got in the car, it felt normal,” the IndyCar team owner said. “Driving the car, controlling the car, was the most normal I’ve felt in 15 years.”

The car uses an advanced infrared camera system, a bite sensor and a GPS system to steer the car around the track. Schmidt averaged 73.712 mph on his 10-mile run, hitting 97 mph down the main straightaway.

Schmidt’s zest for racing has never waned.

The Californian vividly remembers watching guys like Rick Mears winning the Indianapolis 500, envisioning the moment he would make it to the cherished Victory Lane.

His quest officially began in 1997 when Schmidt made his IndyCar debut. Three years later, he was severely injured in a crash in Orlando, Florida, that cost him the use of his arms and legs.

But with a team of some of the best engineers in the world and a nine-month project known as “SAM” or semi-autonomous motorcar gave Schmidt a chance to get back behind the wheel at a venue that has always embraced innovation.

Indianapolis businessman Carl Fisher originally designed the 2.5-mile oval at Indianapolis Motor Speedway to help the U.S. stay competitive in automobile design and craftsmanship. Cars came to Indy to push the limits and test their speed and durability, and more than a century later, they’re still doing things once thought impossible.

How does it work?

A highly-technical series of algorithms controls the vehicle. Four sensors mounted on the driver’s helmet are connected to infrared cameras mounted on the dashboard. They detect his head tilt motions to aid in steering and acceleration. The driver also has a bite sensor device in his mouth, and the pressure of his bite helps control the car’s braking and steering. The GPS keeps the car within 1
