Accelerators have inspired a number of weird inventions. For example, a few years ago we posted about the "Deaccelerator"
which was a device that aimed to prevent speeding by making it harder to depress the pedal in your car once you reached a pre-set speed (usually 50 mph).
We've also posted about an effort to replace the accelerator with a pedal
. The faster the driver pedaled, the faster the car would go. This was designed to give drivers some exercise as they commuted to work.
And yet another odd accelerator invention is the whistling accelerator. The idea is that if the accelerator is depressed too rapidly it will produce an annoying whistle. This will remind the driver not to accelerate too quickly, thereby saving gas.
The idea for a noise-making accelerator goes back to a 1958 patent granted to Philip Kershman of Los Angeles
. He had rigged up an accelerator so that it would ring a bell if depressed too quickly.
Eighteen years later, in 1976, Henry Merriman of Michigan simplified this idea by replacing the bell with a whistle.
He basically took a squeeze toy and attached it to the underside of the accelerator.

Another whistling accelerator was patented in 2012
. Its design was more sophisticated, but it was overall the same idea — accelerate too quickly and the thing starts whistling. The patentees described it as a "vehicle fuel efficiency monitor and signalling device".
Personally, I'm content to drive without any bells or whistles attached to the accelerator.
