What do you do when you’re the one who cut off that SUV you didn’t see in your blind spot? How do you say you’re sorry, especially when you’re going 65 mph on the parkway?

Folks at the National Motorists Assn., a Wisconsin-based lobbying group, want you to give peace a chance. Specifically, they say, hold your two fingers in a “V” with the palm out.

This “apology” signal, they insist, “can defuse the destructive anger and frustration that follow these unfortunate encounters.”

And there’s the rub. Something simple can be easily misconstrued.

As Joanne Gorman of the Twin County Driving School in East Northport, N.Y., says, “There are too many nuts out there. I’d keep my hands down and just have a look on my face that says, ‘I’m sorry.'”

Robert Sinclair, of the Automobile Club of New York, says some European drivers point three fingers of their right hand horizontally at their own head to make an “E” for “Excuse me!” But that gesture “hasn’t made it across the pond,” he says.
