I have, and they suck. But the main reason they suck is because they've been neutered so they're useable for a wider range of people.
Many people who use electric wheelchairs also have problems with fine motor control, seizures, etc. so the joystick has a lot of filtering with associated slow response and staggered acceleration.
I know people in wheelchairs who otherwise had no problems with fine motor skills that had electronically-minded friends help them to upgrade the chairs and replace the control unit. Those wheelchairs go fast after some modding.
Wheelchairs usually occupy the same space as pedestrians - this was a big failing with the Segway, they're not allowed on pavements (aka sidewalks) - in the UK at least - as they're powerful and relatively heavy vehicles. Presumably at least a part of the design is to protect the wheelchair users surroundings and people nearby.

I can see how they could be useful for things like malls and factory floors, in a similar way a kick scooter is. But you know what? Kick scooter is even cooler! The speeds you can achieve on a good concrete surface are exhilarating!
Perhaps the best thing is that able-bodied people will feel jealous when they see it.
TIL that Paul Graham has never ridden a motorcycle.
When riding a motorcycle, your left hand is used for clutch control, your right hand is used for both front brake and throttle control, your left foot is used to shift and your right foot controls the rear brake. Your arms control the front wheel's angle, which creates lean, and balance must be maintained by your whole body at all times:

Motorcycling is hard work; thus the multitude of fitness regimens for motorcyclists:

Ofcourse, even driving a car in a competitive manner requires good fitness.

That's an curious association - I assume this is because only mall cops (and tourists) tend to use it nowadays? :).
It feels slightly unsafe though, just a bit.
To me, this is part of the appeal. Abled folks get to do all sorts of slightly unsafe things: skateboarding, motorcycling, etc. Why should disabled folks be tied to ultra-regulated, super-safe electric wheelchairs with absurdly slow governors?
The edgy vibe is what makes this cool (for me). I'm allowed to choose to ride a motorcycle (which could leave me stranded / kill me / etc). Disabled folks should also be allowed to choose their own calculated risks.
In my mind, that's a huge negative, because it makes it a lot harder to get insurance to even partially cover the cost.
[1] I buy the argument of being constantly trying to balance. These sets of muscle are rarely trained yet very very impact-ful on both body and mood.

You'd probably need to ask a regular wheelchair user, though. Do wheelchair basketballers use seatbelts?
And it looks cool. Completely the opposite feeling of watching someone on a Segway, which could make even the coolest person look like a mall cop.
