A local man's invention could help calm aggressive drivers on local roadways, according to Local 4's Business Editor Rod Meloni.

A device called the Road Rage Terminator promises to bring courtesy to the road.

Don Krzesowiak, a Clinton Township building maintenance worker, wondered what would happen if he started applying politeness to the road, using "the two words you learn first in life, please and thank you."

The idea struck him five years ago while wedging his car into thick traffic, Local 4 reported.

And rather than let the idea pass, Krzesowiak and his wife, Maria, started to work to patent what they're calling the Road Rage Terminator.

The paperwork finally came last year, Local 4 reported.

The couple then went forward with their first design, and, finally, a prototype.

The device is attached to the turning signal wires of a vehicle, and when activating the left or right blinker, the Terminator blinks a message saying, "Please." Once the blinker is deactivated, the Terminator blinks a message that says, "Thank You."

The couple is expected to start building a much brighter and easier to read version of the Terminator for aftermarket sales in the near future, Local 4 reported.

"I think that it's going to be a great help, I really do. I think it's a start and I think that people want to be kind and courteous to each other and sometimes they don't know how to do that," said Maria Krzesowiak.

The couple has started their own company, hired a local sign maker to build the Road Rage Terminator and are doing some of their own marketing research for the device.

"I hope to see it not only in Detroit, but all over the country and all over the world," said Maria.
