Self driving car, ride sharing or is there a better option?

There are a few key advantages here. Unlike the other driverless cars, for this one you don’t have to worry about charging the battery, maintenance, or even a high price tag since it’s made up of 2 pieces: the tow and the chassis. The chassis unit is interchangeable among Pod owners, each unit knowing about the exact location of all the others, which makes things so much easier. All you have to do is make your request, set the destination and you’re all set. If the battery gets low on the way, you will not have to worry about recharging, as another chassis unit is getting alerted and sent to replace the drained one; and the transfer from one chassis to another does not disturb the passenger at all. Finally, when reaching destination, Passenger Pod parks itself into a shared parking facility.
