If the "primary purpose" of the road is through traffic, and the "driving
experience" is like on a major road (e.g. straight, fast, no obstruction, no
give way, etc.), that part of the road is still red / pink.
However, if that road is built like the other residential cul-de-sac with a
lot of slowing and calming features like give ways, curves, or very narrow
such that it become a choke point causing serious traffic congestion every day,
I will think it as residential.
