Millions for mandatory ignition interlocks?

It’s a scene that happens in Washington, D.C. every day. A government worker jumps in a cab, gives his destination, and sets off with a hack who weaves in and out of traffic, shooting the gas, jamming on the brakes, and swerving around pedestrians. Our anonymous, suited passenger watches in terror as the man, mumbling to himself, drives like a maniac through our nation’s capital.

Is the cabbie in this horror show a drunken menace? Nope. He’s just on his hands-free cell phone — an activity that studies have shown impairs drivers as much as a blood alcohol concentration of .08, the legal limit.
