Had my '10 SS for 7 years and never felt the need to change the brake fluid. Though I was fairly gentle most the time. Maybe I was naive.

You're supposed to change the brake fluid in a street car AT LEAST every 3 years or so. If you look at an older commuter that was never touched except for engine oil...you'll find the brake fluid is dark brown, or even black. This is bad.
As mentioned, brake fluid absorbs moisture over time. And moisture will lower the boiling point of the fluid dramatically...for all intents and purposes, every time you take the cap off the brake fluid reservoir, the boiling point has dropped...

.
If you never go to the track, or repeatedly apply the brakes hard...then you'll likely never notice.
But it only takes one or two hard sessions to realize the benefit of a great DOT 4+ brake fluid. As you drive faster, or dive further into corners, you will be braking harder to shed that higher speed and this generates a huge amount of heat. It is recommended that you flush the system after a few track days or so.
