Often times, rescue workers have to wait longer than they want to to get a person out of a car after a crash because they're busy looking up guidelines on how to cut the car apart without doing very bad things, like severing pressurized lines and such. 

Mercedes has now creates a system by which first responders could find one of two QR codes on the car, scan it, and immediately have all the important information without having to page through physical manuals or run internet searches. This could stand to reduce response time and make it so the rescue workers could apply first aid to the wounded more quickly.

No wanting to be a douche-entity, Mercedes released chose not to patent the system, thereby releasing it into the public domain in the hopes that it will become standard across all cars. It's cool to see a corporation acting ethically.
