Ford was recently granted a patent for a mobility solution that, in essence, is little more than a modern car seat with robotic legs attached. It would be used to help drivers who require mobility assistance outside the vehicle -- instead of relying on a wheelchair stored in the car, the car seat could double as a mobility device outside the car.
During standard vehicle operation, the legs would be able to fold away, and the seat would be secured in the vehicle like it normally is. Ford said the legs could operate using either electric motors or hydraulics
The nightmares begin once the seat needs to leave the vehicle. The chair could leave the vehicle one of two ways -- either the legs could extend and the chair could step out of the vehicle on its own, or the chair could slide sideways out of the vehicle, with the legs deploying as it moves.
Keeping the seat from toppling over would seem difficult, thanks to all that weight creating a rather high center of gravity. Even with a bunch of sensors acting as a gyroscope, as Ford suggests in the patent, I still can't imagine it operating much better than some of.
All half-hearted mockery aside, this could be a great thing for disabled drivers. Having one seat act as both wheelchair and car seat reduces complications for people who need it most. Just don't sell the car without having a regular wheelchair sitting around for backup -- I doubt someone would want to buy a car without a driver's seat.
