Over 200 people are killed each year when backed over by motor vehicles. The Supra Auto offers optional Emergency Braking that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The A5 doesn’t offer automatic braking for stationary objects directly to the rear.
The Supra’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The A5 doesn’t offer a driver alert monitor.
