Choose the best answer. Introducing the intelligent bicycleIn recent years, autonomous cars have received much media attention. However, intelligent bicycles are now a reality and are set to become more and more popular in urban areas. It’s easy to understand the reason behind the intelligent bicycle’s rise in popularity. The stresses and dangers of urban cycling have long been recognized. Urban cyclists have to be incredibly focused and aware of their surroundings when riding through busy cities, and the intelligent bicycle helps to relieve some of the pressure from their minds, by detecting threats and providing a kind of warning system in heavy traffic. The intelligent bicycle is able to warn its rider when a fast-moving, deadly object is nearby in order to prevent a fatal accident.How does it do this? The saddle and handlebars of the intelligent bicycle vibrate whenever danger is near: this helps cyclists order to be more aware of their surroundings and of any danger.Bicycle lights are becoming smarter too. Once they just flashed, now they can sense when you are at a junction, a roundabout or heading toward an approaching car. When they sense the situation needs extra light, they shine more brightly, keeping the rider safe.The intelligent bicycle also comes with a camera system that uses image processing to detect multiple vehicles at the same time. If intelligent bicycles continue to evolve in this way, accidents could become a thing of the past.(1) (单选题)What is the purpose of this article? A.To point out the dangers of intelligent bicycles.
