When was the last time you ever hit more than two green lights in a row?

I don't know how common this is in other places, but when I learned to drive
in downtown Des Moines, Iowa, where the speed limit is the standard 20 miles
per hour business district limit, you can go through all of downtown
(guessing 6 to 10 lights) with a green light, by going exactly 18 miles per
hour. I always thought it was pretty cool, and pretty funny how people that
didn't know about this would accelerate as hard as they could at each green
light, go well over the speed limit, only to get to a red light at the next
intersection and lose all their efforts at going faster by waiting at the
light. They made their own stop and go traffic instead of riding the green
light "wave"...
