Thought about thought controlled Bicycle

This thought from the comments to that article:

 [QUOTE]And what happens when you see a hot chic in a short dress? 

So much for thought controlled gear shifts.

Wow, what happen when you see a hot chick!? So much for gear control.

depends what you want to do with his hot chick. Follow and race her and you automatically gear up, slow down and oggle then you'll gear down

I really don;t get the point of this for a bicycle which is so simple to operate gears with little effort with mind or body.

How about a brainwave operated car which cuts in when the driver is not focussed on driving (Like on the mobile phone, seeing a hot chick or guy, road rage, on drugs or booze) it immobilses the car till the driver gets with it.
