There’s that frustrating moment while driving we’ve all experienced: you’re cruising along, alone as far as the eye can see, when you’re forced to stop for a red light, wait, and accelerate away. This is only for the convenience of the machine.
All momentum is lost to braking, and all that gas spent to get going again is a waste of energy. If the light had only been smarter, ‘seen’ you coming, or aligned with the more common traffic pattern, you’d save on gas, and the earth would fair a little bit better.
I wonder how much energy waste in aggregate this amounts to across the country. Anybody fathom a guess at how much gas could be saved by slightly smarter street lights?
