Mobility-as-a-Service has moved from a concept for the future of urban transportation to reality in some of the big cities of the world. There are numerous projections about Mobility-as-a-Service market. For example, Accenture research shows that by 2030, revenues from manufacturing and selling vehicles (around €2 trillion) will be only marginally higher than they are today, and that profits from car sales will decrease (from around €126 billion to €122 billion). By contrast, revenues from mobility services are predicted to reach almost €1.2 trillion—with profits reaching €220 billion. Whatever its form might be, there is no doubt in minds or strategies of the biggest automotive and transportation companies that demand-responsive and integrated transportation services are what users demand today. It is essential to survival and prosperity of all mobility providers, whether they might be car sharing or car rental businesses to adopt this trend and tailor their service to be used as MaaS.
