If you have a multi-seat peoplemover vehicle, there is often quibbling within a family about who gets to sit where.
Today’s invention is to have the seats in such a vehicle movable -like the pieces in one of those sliding puzzle squares.
Seats can slide so that there is always one empty space and thus any arrangement is possible. The sliding might also occur whilst in transit.
In addition, this allows individuals to preserve their complicated seat settings, rather than having constantly to reset these -as well as permuting family members to achieve minimised social friction.
