s camera. Another vehicle approaching at high speed on a collision (碰撞) track might not be visible until it'

s too late. This is w hy vehicleto vehicle communication is undergoing rapid development. Our research show s that cars w ill need to be able to chat and cooperate on the road, although the technical challenges are considerable. Applications for vehicletovehicle communication range from vehicles driving together in a row, to safety messages about nearby emergency vehicles. Vehicles could alert each other to avoid collisions or share notices about passersby and bicycles. From as far as several hundred metres aw ay, vehicles could exchange messages w ith one another or receive information from roadside units(RSUs)about nearby incidents or dangerous road conditions through 4G netw ork. A high level of AI seems required for such vehicles, not only to self drive from A to B, but also to react intelligently to messages received. Vehicles w ill need to plan, reason, strategize and adapt in the light of information received in real time and to carry out cooperative behaviours. For example, a group of autonomous vehicles might avoid a route together because of potential risks, or a vehicle could decide to drop someone off earlier due to messages received, a foreseen crow ding ahead. Further applications of vehicletovehicle communication are still being researched, including how to perform cooperative behaviour. (1)What is the first paragraph mainly about? A.
