In the middle of the night, it is difficult for drivers to recognize people or things in front of them. I accidentally hit it, and it's even harder to tell if it's a cliff. So, I think we can install a reconnaissance system in the car. It can observe whether there are people or things in the distance and whether there are cliffs. If there is someone, it will call the police and tell the driver to slow down. If there is a cliff, it will make the driver suddenly brake and stop driving. But when we pedestrians walk in the middle of the night, we'd better wear fluorescent vests, which can make drivers see more clearly, and we'd better wear dark clothes during the day.

Golden idea 2:

My third golden idea is designed for drivers who drink and drive. This device is installed in the place where cars are made. This gadget is as smart as an electronic dog nose. When the driver is ready to get on the bus, the exploration system will start. It can detect whether the driver has drunk alcohol. If there is alcohol, it will automatically shut down all systems, and then warn: "Don't drive while drinking, or all systems will shut down ...". The driver's car keys can't open the door, let alone start the car. If you are a non-drinking host, explore the system, and it will automatically release the system control and open the door.

My golden idea is not bad! I hope people can think of more good ways to greatly reduce traffic accidents.

Less car accidents, more happiness, beware of car accidents, happiness killers.

On TV, we often see parking poles at the entrance of the community, as well as on the expressway. I thought, why not move this machine to the crossroads? It can replace traffic lights. When the red light came on, the long railing fell down. The green light turned on and the bar went up again. When the red light is about to light up, it will automatically send out a green warning light. This machine can not only direct vehicles, but also serve as traffic lights for pedestrians.
