In America, folks with mobility issues must turn to aftermarket companies (like this one) to modify their vehicles for their needs. But in Japan, where the population is aging, design considerations for the disabled are baked in right at the factory. Carmaker Daihatsu manufactures an entire "Friendship Series" of automobiles (in the company's bread-and-butter size class, the kei car category) that are designed to make life easier for those with mobility issues.

The company has different models aimed at different needs and size requirements. To carry a wheelchair-bound passenger, Daihatsu's "Sloper" design features a retractable ramp mounted in the rear. Buyers can opt for the smaller Tanto or the (relatively) larger Hijet or Atrai models:

For the passenger who is not wheelchair-bound, but finds ingress and egress difficult with a conventional car design, they offer the Atrai Rear Seat Lift:

For the driver who is not wheelchair-bound, but finds ingress and egress difficult with a conventional car design, Daihatsu offers the Move Front Seat Lift and the Tanto Welcome Seat Lift, whose driver's seats both turn and lower electronically:

Lastly, for the driver that does use a wheelchair yet is not completely confined to one, the Tanto Welcome Turn Seat allows them to wheel over to their car, stow the chair in the rear via a small built-in crane, and access the driver's position via the turning seat:

The question is: As America's population continues to age, do you think our domestic manufacturers will start to do what Daihatsu's doing? I'm not so sure--while America undoubtedly has or will have greater numbers of people with mobility issues than Japan does, I haven't seen any U.S. car companies take an interest.
