I think that depends quite a bit on the people in question, and quite a bit on what types of vehicles come to market to support this usage. Compartmentalized vehicles with shutters of some sort might find quite a bit of use. People that don't own a car and want to get around cheaply might find quite a bit of use. Designated child-only vehicles for school shuttling might see quite a bit of use. A small stretch vehicle with lots of doors would be perfect.[1]
