Traffic Signals

Can updating traffic signals increase the mpg you get in your car? BWM is saying yes. With coming to a stop each time at a red light and then starting again uses alot of gas which is why BMW has been pushing officials to update traffic signals so they are more friendly and traffic is moved better. With this car companies have been finding solutions as well by finding a way for your vehicle to not comsume so much gas while not moving. BMW has done this with there BWM 530d test vehicle with a a fual efficiency of usually 22 mpg to 42 mpg. With this simple change it could reduce the amount of fuel used each year and I think would help everything and everyone out as well.
