I had the light come on intermittantly. Turns out it was a defective brake light switch.

Other than that, I think it comes in handy while being a little too heavy-footed, and driving on surfaces with poor traction.
If the roads are drenched or covered in pea-gravel, you can stomp on the gas, and not slide (much), nor spew forth gravel at others (including yourself).

A disadvantage, is that you can't smoke the tires.


hope this helps...
