Here's a noteworthy quote I stumbled across this evening:
"The average stop sign in the U.S. causes an average of 20 tons of carbon dioxide to be added to the atmosphere yearly." --

Now that I’m driving a full hybrid vehicle, eg. one that is capable of running on its electric only motor during low demand periods like stop signs, applying the brakes, Reverse, and many situations under 30mph, I’ve noticed how noisy and smelly stop lights/signs are. How/why so? Because everything around me is running its gasoline (internal combustion) engine, and I’m whirring along in electric only “stealth mode”.
Knowing our government, they’ll ban stop signs and stoplights and claim it’s an “environmental initiative.”
