It's all theoretical. Do you see it actually working out this way? When and where?

> regulators just, you know, look at the design of the chairs to evaluate them for certification. But customers could do the same thing for themselves, at less cost (what, you think those government regulators work for free?). So the regulations are actually adding zero value. But they're certainly not adding zero cost.

I have little idea how to evaluate the safety of an electric wheelchair, and don't have the time to acquire the expertise to learn how to do that with everything I buy. But we all can chip in and pay someone, who has the expertise, to do it once rather than than millions of people doing it redundantly.
