>>7815335Let me tell you about Pittsburgh, friends. This 2-D layout doesn't do it justice.
Due to being nestled in the mountains, there is a 3-D "adventure" in attempting to navigate the city that is not for the faint-hearted. In particular, if you drive a stick shift, there are crossroads with stoplights on 30 degree slopes, sometimes five- or six-way intersections, with buildings and mountain topography randomly obscuring visibility for other traffic. Which may just be cars, or maybe coal or steel trucks packed with 40 or 60 tons of whatever they're transporting.
Did I mention random train tracks & crossings? As you can see, 90-degree, right-angle, four-way intersections of just two roads are virtually non-existent. And by the way, those 15- or 20-degree grades? They aren't necessarily perpendicular to the direction the road is going, or even from one side of the road to the other.
And, ahhh, Winter. When 2 to 6 feet of snow may be coming down any given night or afternoon. Businesses & schools don't really do "snow days," unless it's unusually brutal, because if they did for merely a foot of snow and some freezing rain, then nobody would leave their house for five months. You just get up in the morning, shovel three feet from around your car, and go to work like normal, or walk out of the grocery store and brush 18 inches of snow off your car and drive home.
Pittsburgh drivers are some of the best in the world. Darwin is a brutal master.
Thank you, OP. Fantastic thread.
