A vehicle sold in Hungray called the Kenguru is designed so a person using a wheelchair can easily enter the vehicle. Cool Hunter explains:

The car’s interior space has no front seat - just a space built to house the driver’s own wheelchair so all he/she has to do is simply roll in through the extra large car doors and into position. The wheelchair locks into place, within easy reach of the car’s controls which are centred around a joystick. It’s light years away from the current options for disabled drivers, which involve having to hoist themselves into the driver’s seat of standard cars.

A comment on Boing Boing’s entry for the car says it is not a concept car and can actually be purchased in Hungary. The 19th Floor is concerned the vehicle could easily be crushed and wonders where the passenger would sit.
