You can buy mobility scooters for under £2000. e.g. https://www.mobilitypower.co.uk/product/fastest/ $65k is an obvious rip-off. > Medicare is likely what is requiring a regulation grade wheel chair, not the users themselves. It's a shame Medicare can't just give the users cash and allow them to choose their own wheelchair; both Medicare and the users would win. |

1)The chair has to be comfortable enough to be in almost constantly - for someone whose body may not be shaped the same as most other people's. It may need to be designed in a way that makes it easier for the user to get in and out of, unassisted. That means a substantial part of it is customized to each user, probably in consultation with medical professionals. It may need to carry medical devices/equipment.
2)The chair has to be navigable in indoor spaces with a fine degree of control, by someone who may have lower motor skills and range of motion than others. So it may need customizable response time, input smoothing, and acceleration.
3)The chair cannot, under any circumstances, make an un-commanded motion - which could easily kill the occupant (ie going into traffic, or down a steep hill, or off into water.) That has implications for the physical controls, the electronic controls, and mechanical drives (I'm guessing many chairs have electrical locking, and can use the motors for braking.) Similarly, the chair has to be very reliable, or that could kill the occupant (say, a fire or other emergency where they are) or otherwise be a major inconvenience. If you're unable to move much from your chair and, say, your cell phone is in another room - you're varying levels of screwed.
4)It has to be designed such that fire would be a very low risk.
Are they probably more expensive than they need to be? Yeah. But I'm sure it's nowhere near an order of magnitude, and your comment is pretty ignorant.
