And yeah it must be hell dealing with those hills in Pittsburgh during the winter.

Well... yes it is. Canton St. in Pittsburgh is the most widely-accepted steepest. One could take portions (like that SF street study did) of Pittsburgh's streets and find steeper grades contained within their lengths as well.
The numbers you are posting are only for
very short segments of SF's steepest streets.
From the articles you cite:
1. Bradford above Tompkins (41% grade)
2. Romolo between Vallejo and Fresno (37.5% grade)
3. Prentiss between Chapman and Powhattan (37% grade)
4. Nevada above Chapman (35% grade)
5. Baden above Mangels (34% grade)
6. Ripley between Peralta and Alabama (31.5% grade)
7. 24th between De Haro and Rhode Island (31.5% grade)
8. Filbert between Hyde and Leavenworth (31.5% grade)
9. 22nd between Vicksburg and Church (31.5% grade)
10. Broadway above Taylor (31% grade)
As you can see, these are ALL the steepest short SEGMENTS of SF streets. That's not the same thing as steepest street.
For instance, for SF's steepest street...
"With an astonishing 41% grade, Bradford Street, in the hilly Bernal Heights neighborhood, is the city’s steepest (at least of those surveyed). Admittedly, this stretch is quite short: the majority of Bradford Street climbs steadily at about a 24% grade before exploding into a 30-foot stretch of 41% paved road."
Only 30ft at 41% grade... obviously very steep. But it's the length of a short driveway at that grade in front of that bluish house.
Certainly not the steepest street. Maybe steepest street
section, but studies like the ones you cite have never been done on Pittsburgh's city streets, nor in all of the hundreds of surrounding in the metro. In winter, you simply don't go down them.
