Part of the problem with marketing a balance-sensing mobility device to a mobility-impaired person is that they often have imperfect balance control themselves, and depend on rigid motion supports, i.e. walkers, canes, etc.
Seated on a single-point-of-control mechanical system, with no balance reference or rigid point of support available to them and with no safety system monitoring the safety of a proposed move, they might be accidentally launched from a sidewalk into street traffic, or down a flight of stairs, or otherwise into danger.
Unlike an automobile or a wheelchair, this device apparently has no independent braking system other than putting down your feet...which would run the risk of being tipped off in motion, for an older, slower-reacting rider.
I have no idea what Honda's marketing strategy for this may be...product, or technology demonstrator/reputation builder like their dancing robots...but surely they are aware of the issues involved in a single-point-of-control, non-safety-monitored human mobility system.
