The seats would attach to each other and also be harnassed to other transport mechanisms. For example you would exit the plane without getting out of your chair. The chair would get back onto tracks or be attached to a pully and it would then get put onto the truck so you can be brought to the train that will bring you to your home town.
The airplanes would be slotted along the sides, you're transportation pod would snap in.
by the way if you have one of these (in my future better system of transportation) you could go all the way to where ever without ever having to get out of your chair.
At some point people do need to stretch . . . so that's probably not possible.
or . . . for the better healled, with more resources, they don't just have a seat, they have a whole lounge car.
When they travel with the family they drive to the airport and leave the chasis in the garage. The body detaches into the airplane and away they go.
when they get to rome they rent a chasis and they use that.
Dad drives.
see how fiction is fun and can lead to better future.
it's better to make up stuff that would be good for people than to create conflict by saying what kind of violence would happen given . . . whatever.
