I know quite a few people with dyspraxia who can drive and who drive well. But I know many more who cannot. It all depends on the severity of the dyspraxia and which areas are affected.
One of my friends has Dyspraxia, he is brilliantly creative and is clumsy but only mildly clumsy. I would never have thought of him as clumsy until I told him I had dyspraxia and he said he did too. He's not as academic as me as he also has Dyslexia and struggles to read, when he was at school he didn't get much help and it put him off schoolwork. He did his degree in a photography as it utilised his creativity.
Whereas I do not have Dyslexia with my Dyspraxia, I have Dyscalculia and struggle with maths. I am much more clumsy, I spent half my childhood on the floor. I have near falls up to 10 times a day. I am constantly bumping in to things, grating my nails in the cheese, peeling my thumb skin etc. My spatial awareness is much worse. As I'm also hypermobile that makes me clumsy as well, plus fibromyalgia causes spatial awareness and clumsiness issues - I got a hatrick! I went down the academic route as I was hopeless at everything else, I can't do maths, I can't do music, sport and dance are a no no, my teachers always said if only I had the ability to balance because my body is so flexible (I can kiss my toes standing up) I'd have been a great gymnast. Running's out as I hand flap and don't appreciate the 'spaz' comments I get when I run. So I embraced the fact I'm a ridiculously fast reader and went down the social sciences route :)
At least I'm fucking ace at thumb wars though, I'm short but no bugger can pin my thumbs down, not with the places they can go
