I used to work in Rent a car industry for a couple of years then i became a board member for car rental company and looking into what changes are taking place i expect that within 10 years there will be no need for a human being to deliver the car since we have self driving cars, it will be fully depending on AI bots from estimating the cost of operation, it will have massive transformation depending on the technology. Imagine that the cars will be mostly electrical, mostly self driving and it will require less maintenance meaning less cost, the competition will be very sever the pay per Kilo/per mile will expand dramatically. It is going to be "per demand " industry and it will mingle with finance leasing, leasing ending with ownership etc.. hope this helps.
