You do not buy a hybrid to save cash. You buy a hybrid to save fuel. TCO = total cost of ownership Several folks in my family own Corollas, Accords, and such. Because over their weekly lifecycle of the vehicle they spend less on the extra gasoline than they would spend paying off the hybrid. Plus, in this area, you end up on the highway at somepoint going most places. Urban sprawl, baby. Don't get me wrong, I love the Volt concept (and would secretly love to buy a Prius) But when the $ hits the counter, the inexpensive economy cars end up being cheaper for most of us. I used to drive an F-150. Mine got like 16-17mpg. I did the math. The total outlay of purchasing a new, higher mileage vehicle, ended up being greater than about 10 years worth of the gas I'd save. Even if gasoline runs up to like $4-5 a gallon, I'm better off financially staying in my current vehicle than I would be trading it in.

Agreed. Expressing your opinion by referring to a seated elected official as being "dumb" is in no way a racial slur. In fact, I believe it is covered under #1 on that bill of rights thingy. But then more and more of our "free speech" is being trimmed away as being racist or obscene or (heaven help us) "offensive" merely because someone else doesn't like hearing it. I missed the part of the Consitution banning or even limiting "offensive" speech. Where was that exactly?

I'm guessing they mean that if YOUR car has a detection circuit, it could receive the digital LED communication from the other car and then either play an alert sound or perhaps trigger the brakes for you. The tail lights would not talk directly to you.
