just found that the VSA is availble in the UK on the ES model without having to have the nav installed, interesting

 

Hope this doesn't sound completely dumb.. but how did you test it in a parking lot with it off?.. isn't it always "on".. somehow?.. I picked up my car and was only driving it for about 5 days and had to leave to come back to new york city-- so i haven't had a chance to really play with it much at all-- but soon!! soon!!

 

There is a VSA off button - look low and to the left of the Steering wheel.

Here is a nice video that explains VSA:

If you are deaf or no speakers on your computer:

YouTube - Honda VSA

And although not Honda tech, it's got the same effect:
