Here's a new one: University of Utah researchers have created a car ignition key that prevents the driver from talking on a cell phone or sending text messages while behind the wheel, Cellular News reports.

"The university has obtained provisional patents and licensed the invention—Key2SafeDriving—to a private company that hopes to see it on the market within six months at a cost of less than $50 per key plus a yet-undetermined monthly service fee," the report said.

Ronn Hartman, managing partner of Accendo LC, said in a statement that the company plans to license the technology to cell phone carriers as part of their service plans, instead of selling it to customers directly.

Oh, and a personal note after the jump...
