Abstract
With the growing development of Cooperative, Connected, and Automated Mobility (CCAM), questions arise about the real impact of this innovative mobility on our daily life. CCAM originally promised to improve road safety. It is now a holistic solution for future mobility: the CCAM is there to optimize traffic, which can translate into strategies for reducing energy consumption or polluting emissions, without compromising road safety. The capability of CCAM is dependent on the reliability and robustness of its components, as it will be making life-impacting decisions. It is therefore necessary to be able to guarantee a high-level quality of sensors, communication, software, and hardware architecture. In this mobility ecosystem, the infrastructure and data that it will be able to produce is at the heart of current research issues. This paper addresses the following question: Are the Connected and automated Vehicles (CAVs) the silver bullet solution with which to answer the issues of the current mobility systems? This question is discussed by investigating the technologies used, the digital infrastructures, its robustness to cyber-attack, and their relationship with the claimed benefits on safety, energy and pollution management, traffic optimization, deployment strategy, and a link with the new generation of road infrastructures.

In Gruyer et al (2017), a study is proposed about the embedded sensors technologies used in perception, FIGURE 9 | Electromagnetic spectrum: a better understanding of the operating range of each type of information sources used in Connected and automated Vehicles (CAVs) development
In Mersky and Samaras (2016) some results show that Automated Vehicles (AV) following algorithms designed without considering energy efficiency can degrade fuel economy by up to 3%, while the use of specific and well-tuned strategies focused on energy efficiency could provide equal or slightly better results than the existing EPA (Environmental Protection Agency) fuel economy test results
Summary
Within the context of an increasingly marked international competition, economic growth is often based on technological innovation. On a recent Hype cycle carried out by the Gartner cabinet in 2019 (Gartner, 2019), the so-called level 4 Automated Vehicles (AV) has entered a phase of disillusionment, showing the generalization of fears on this subject. This topic of over-trust, according to Dixon (2020), is influenced by marketing managers who overstate the AV capacities. The following sections analyze the benefits, advantages, limitations, and weaknesses of the CAV in terms of safety, energy and pollution, and traffic. The topics require further research, and improvements will be identified and discussed
