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.

In 1970, there was a strip of highway in Greenville, SC that was like this. In one
direction, you could travel five miles or more without a red light if you held to
within about 2 mph either way of the speed limit. In the other direction, you'd catch
exactly one red light doing this.

By contrast, there's a strip of highway in Pennsylvania on which the State posted a
speed limit around 55 mph. The local traffic director wanted 25 mph and got
overruled, so he set the lights to all go red for anyone traveling faster than 25
mph.

This marriage is off to a shaky start. The groom just asked the band to
play "Your cheatin' heart", and the bride just requested "Don't come home
a'drinkin' with lovin' on your mind".
