I gave up, I'll just have to grow baboon arms. I've had some handicap customisation modders look at it, and it's possible. But then I'd have to drop airbag to get it through govt. control, because the airbag functionality is only tested with the factory length of the steering wheel.
Which is stupid imo, I mean, what's the difference between me having the airbag 10 cm closer to me, and a shorter guy sitting 10cm closer to the airbag?
Well, that's bureaucracy in a nutshell.
