This one is the Firefly. It's an attachment that clips onto the front of a wheelchair. I've seen videos where a person can even navigate rough terrain, such as a dirt hiking trail.
There's also a car, the Chairiot Solo that is designed specifically for a solo wheelchair driver, There's also a version of this that includes a fun sunroof. This isn't a car that can be driven on the highway. It has a speed limit of either 25 or 35 miles per hour, depending on one's location/local laws, and it only has a range of 50 miles. Obviously, there are more powerful vehicles that feature wheelchair lifts, but this is still a wonderful invention.
I'm sure there are other new inventions out there. If you hear of any, let me know. I'm always interested on ways to make the world a more accessible place for everyone.
Have a wonderful day!
