Since the invention of automobiles, engineers have spent endless efforts to enhance their safety, operability, and fuel efficiency. The rapid development of electric vehicles (EVs) has transformed them into movable computing hubs, equipped with ample sensing, computing capabilities, and battery power. However, the placement of all the vehicle's sensors within its structure poses limitations to its sensing capability, consequently restricting potential applications. Meanwhile, unmanned aerial vehicles (UAVs or drones) offer aerial-perspective sensing capability from flexible viewpoints, processing which in real time can complement cars' sensing and enable novel applications. In this paper, we introduce our vision of how the real-time collaboration of ground and aerial vehicles can enable innovative mobility solutions. We discuss the system architectures, potential usage scenarios, and enabling technologies for supporting drone-car collaboration. Furthermore, we examine the latest technical advancements in the field and shed light on the promising opportunities that lie ahead in the future. Overall, this article provides a comprehensive understanding of the potential and significance of real-time collaboration between drones and cars in revolutionizing future mobility, improving fuel efficiency, and enhancing driving safety.
