This is a great example of good people getting screwed over because of bad people.
I actually like these things. I've told the missus a hundred times I want to get her one. Her vision is good enough she can get around okay (blind in one eye, near sighted in the other), but not good enough she can get a driver's license until science advances a lot more.
We've gotten her 3 or 4 different ebikes now to try to find something she's comfortable getting around the city on with her disability. Really one of these things, with roof, would be perfect for her, but I think she's worried that there is a lot of stigma associated with them if you get out of one and you aren't 184 years old.
Like you pointed out, a lot of people assume if you're in one, it's because you got a DUI, and I think she's worried she'll be looked down as if she's an alcoholic because she's fit and in her early 40s. In reality she has never had a license and I wish she drank more because those are the funnest nights lol
For someone like her, taking the roof off wouldn't make her go any faster, or any slower, it would just make her more exposed to the elements and more vulnerable.
