My Saab has two unusual buttons on the gearshift labeled S and W. (Saab owners like to call those kind of things "quirks.")

S activates "Sport Mode" telling the car to shift sooner, providing greater acceleration. "Winter Mode" does the opposite, actually skipping first and second gears to prevent slippage on ice.

That W button isn't doing me a lot of good sitting in Southern California traffic. What I really want is a "G" for "Gridlock Mode" button.

Ideally it would let me keep my foot on one pedal the whole time and have the car default to a stopped state. The brake seems like the right pedal, but only if the Mode can be smart enough to not ride the brakes the whole time, and instead rely on ultra-low idling and engine braking. (If it were the accelerator, I would expect a braking effect with my foot off the pedal.)

This would reduce the chance for fender benders, since I'm not constantly switching pedals, lengthen the life of my brakes and conserve fuel, but most importantly, help me cope with the insanity.
