This is one of those "Now why didn't I think of that?" ideas. Whenever we get on the highway for a long motor trip, I use the car's cruise control to set our "pace". As a precaution, I always keep my foot hovering over the brake pedal, "just-in-case". Studies have shown that when a car is in cruise control, braking response times are much quicker. This is because the foot only has to move down on the pedal, as opposed to lifting it off the throttle, moving it over and then down again on the brake.
The problem is, after a very short time holding my foot up in front of the brake, it gets very sore and I have to rest it flat on the floor, away from the pedal. This, of course, defeats the safety aspect of having my foot "at the ready" to punch the brake whenever the idiot in front does something stupid, like swerve and slam on his brakes to miss a cat in the road.
Enter the Chindogu Support Brake Pedal, attached, as in this case, via double sided tape, or for more permanent installations, with heavy duty clamps, directly to the brake pedal.
Now, when I drive with the cruise control on, I can rest my foot against the Chindogu Support Brake Pedal all day without having to use a muscle to support my foot. If something happens, all I have to do is mash my foot down, and the car comes to a safe stop.
