The CabiBUS design is based on this estimated minimum cabin interior size:
Height 170 cm, 66,9 in
Length 100 cm, 39,4 in
Width 95 cm, 37,4 in
Now, when the first cabin prototype is built, it feels very roomy, it should be no problem for anyone to spend up to an hour commuting from home to work (CabiBUS covers a commuting distance of up to 100 km).
As can be seen in the images, the height can probably be reduced a bit, making the CabiBUS lower and so increasing the range. Still plenty of room for the tall person, here 196 cm, 77 in.
There will be a very comfortable seat, the one in the pictures is just a standard chair.
2 persons is possible! Testing the prototype it became obvious that
each cabin actually have room for two persons (depending on size of course). As long as they travel together, with the same start and destination, a parent and child, or a couple, can share one cabin, and one ticket. This substantially increase the capacity for CabiBUS, up to 13 passengers, including one wheelchair passenger.
