In EU (and probably elsewhere), there are strict rules for the stability of power wheelchair. One such rule is "On a incline of x% (x chosen by the manufacturer), pushing for max speed from stop should not lift the front wheels"

To achieve that, the max acceleration must be quite low (software controlled), and the whole experience is sluggish, like trying to steer a car by pulling on rubber bands attached to the wheel.

From the moment I found a way to overcome this, I never went back. I know that I can hurt myself if I do something stupid, but I prefer this hypothetical risk instead of cursing 100 times a day because I cannot move how I want. It has been 10 years and I never got hurt.

I understand that such "high" risk device cannot be sold, but forbidding someone to change this is like inflicting a second handicap on him.

I suppose we all have, or should have, the right to try stupid things. Sometimes experience and competence are more important than 100% safety. Your comment made me realize how limiting it would be to be physically incapable of taking even the smallest risk.

That is a very poor regulation. Why enforce wheel lift? What matters is that the chair doesn't tip over - that the center of gravity remains in the center of the four wheels.
