Touch & Taste - Not much use on a bike unless something has gone horribly wrong.
Smell - I do occationally smell a car, but I don't think it's of much use on a bike, espeically as you're more likely to smell something you're heading towards
Sight - Is the obvious one - Do deaf people have better eye sight? And even if they do, would it make that much difference as a cyclist? I tend to think that if you can't see a car, you're in trouble anyway...
Well, maybe you're right there, technically, I don't know for sure as my hearing (I believe) is pretty good. I guess touch is the obvious one that's improved, but no, not much use on a bike. Sight maybe not, but ability to appreciate what can be seen rather than ignoring a quick glance - quite possibly.
My point is still valid though - hearing is a very useful additional sense
