Very steep streets should still be preferred to lifting your bike up a staircase

[graue]

Pushing a bike on the sidewalk is easier than lifting it, so very steep streets should still be preferred to steps.

This route from Embarcadero Station to a one-block street called Calhoun Terrace is recommending lifting my bike up the Filbert Steps.

It is probably doing it because the only non-stair way up involves one block that's a 16%/17% grade according to HillMapper: Union from Kearny to Montgomery.

If I'm reading this right, a grade of 16% or higher has a penalty of REACH_DESTINATION, the highest value and the same value assigned to staircases, so it wouldn't be preferred over "schlep your bike up this enormous staircase."
