That bus driver is awesome!

You can get a joystick controlled chair that can go off road, and put knobby tires on most chairs. It's a matter of money and mess for those who are in chairs.

In this case it has to do with the design of the chair.

It's a pretty big leap to assume this design an improvement in how a chair is controlled, especially by a quadriplegic.

It would be a matter of preference for most paraplegics, but that's generally a matter of convenience. From that point of view I don't think this is an improvement at all over a joystick.

Joysticks are very intuitive and require almost no effort. Leaning back and forth and side to side is not so intuitive and requires a lot more effort.

One thing this chair does offer is "fun". I think it's cool as can be and I'd love to take it for a spin.
