Dear NSA--about bar codes

Dear NSA...

Rick and I were on the Champs-Elysèe yesterday and we saw this poster with the stripes on the roof and striped side-view mirrors, which I love.

But I have a question. I've read that all cars are going to have tracking systems which means the police or you guys can find a car anytime, anyplace.

I know there are ways to track cars because I used one in Murder in Ely which will be out in April. And there are companies that sell the products that allow it on the Internet. But every car automatically? Is it true?

But when I looked at the stripes on the roof, it looked like bar coding so maybe that's how you'll do it.

Love,
DL
