The basic understanding of the idea is that in future, best travel services are in public transport units. Personal cars are not allowed for fancy nomadic devices, buses, trains. Car-pool vans will have all fancy services. The service production and support systems of advanced private public transport services has been developed taking into account security and safety services.
There will be 3-dimensional (taxi) traffic navigation. Radar-based collision avoidance systems are implemented in vehicles. Autonomous driving is common. There also may be flying taxis that follow the road networks.
Car sharing will be based on electronic vehicles. Accurate travel and travel time information to make best choice will be commonly available. Personal travel device service (rent) is ready to be used on (large) public transport stations. There also may be some kind of relaxing system as service in the vehicles. Comfort on-demand at a price!
A major challenge is the integration of the liability and accessibility issues of the various aspects of these scenarios, and these need to be simulated to determine the degrees to which such polices could work and the reactions of people to the opportunities and contsraints-and of course how to handle mixed systems where existong vehilces may be allowed tooperate but only as shared 'taxis'.. and the libaility and revenue mdoels that would allow these to work.
