The first urban automatic emergency braking assistant appeared in Volvo vehicles nearly a decade ago. At the time, it used an infrared laser camera, capable of forcing the vehicle to brake on its own at speeds below 18 mph (30 kph), to avoid (or reduce the impact of) a collision.

Since then, these systems have continued to evolve, and nowadays some cars such as the Mercedes-Benz E-Class and S-Class can brake alone at up to 124 mph (200 kph), combining long-range speed camera data with stereoscopic cameras to detect pedestrians and avoid running over.
