Future mobility concepts, will most likely result in fully autonmous shared vehicles for urban transportation or the last mile.
E.g. I usually use my car for about 40 minutes every day commuting between home and work. That's 1/35th of 24h and 1/15th of a 10h eindow. Considering that it would need time to pick up someone else, I'd estimate that one car could serve around 25 clients. Also getting from A to be should be quicker because of 15x less traffic on the road, and AI's (hopefully) not driving like idiots.
People will need to get used to not owning their own vehicle.
