Safety training, simulated childbirth scene training, driving skills training and VR training are all indispensable. Interestingly, the safety training course also teaches couriers how to walk, how to honk when driving, how to pull heavy objects, and how to pay attention to pedestrians and vehicles around when driving. UPS has 12 exclusive courier training bases in the United States, which is called "devil training camp". In the training camp, couriers have to learn defensive driving skills for 5-9 days. Learning scenes include: classrooms, physical vehicles, paths, main roads, pattern distribution scenes, and how to avoid dogs. On 20 17, VR training was started, and VR helmets were issued to drivers. Through the 360-degree virtual scene of VR, drivers learned how to avoid danger in the street.
