Plenty of riders can stand, walk and climb into a vehicle unaided on a good day. On a bad day, after a treatment, or across an icy January parking lot, the same trip becomes genuinely risky. Ambulatory transportation exists for that gap.
Jomia's ambulatory riders use canes, walkers, rollators or nothing at all. What they share is the need for a driver who parks close, opens the door, offers an arm and does not start the engine until everyone is settled.
Vehicles are chosen for easy entry rather than sporty styling: a sensible step height, grab handles, wide door openings and room for a walker to travel upright rather than wedged into a trunk.
