All green lights? About 6min.
A single red light? Up it to about 15min. Traffic lights are
ed in my area, and they stack rows of them bitches on every street. Go a quarter mile and you're hitting 5 lights, then you're turning on an interstate with a light about every quarter mile after that, and then I turn onto another off-road with 4 more lights stacked in the half mile it takes me on that road to get to my center, plus those train tracks that every UPS center seems to be located next to.
[EDIT: ~3.5 miles]
