All the BS about global warming and going green...
Why aren't cities going to make on every road that is having multiple traffic lights....a "GREEN WAVE"...that would make less stress and annoying moments for drivers, less accidents by hiting the back of the car in front of you...and it saves gas, since cars keep driving...maybe add a sign to say at what speed the green wave will work and it will help a lot!
And you don't have to be Al Gore to know this
