First, I too am glad you're okay, Will! (Obviously, we all are.)
The downhill issue is a general bike lane design issue that I feel like some traffic engineers don't take into account enough. (Not that there's a bike lane on State Street downhill to the bridge, but this is an excellent reason NOT to have one there. OTOH, centered sharrows would be cool, IMO.) I'm not thinking of any particular problems in Portland, but heard about a particularly dangerous one in Seattle, I think it was, that was actually a two-way separated lane. So you had cyclists, some inexperienced, passing driveways and other unsignalized intersections quickly from an unexpected direction. I'm not sure of the current status of that installation. But in general, I hope that bike lane designers remember to consider more than just flat width in their design decisions.
I recall that we saw the plan for this Elm Street design a year or so ago. When I first heard about it, I did initially have concerns about it being downhill. But I actually felt better about it after seeing the design, and having ridden in it last week, primarily because the bike lane is so wide, from having reduced the number of travel lanes (NOT "car lanes", please; framing matters) from two to one. There looks to be plenty of room to stay away from parked cars, and doesn't seem that much different geometrically and experientially than just riding in the rightmost of the two former travel lanes, which we'd all been doing safely for years. (Okay, I admit I haven't researched crashes there; but I never heard of any.)
As for the bike lane being next to buses at the Pulse, I haven't tried that part yet, but I'm not initially inclined to be too concerned about it. Obviously dooring is not a problem from buses, and there is a buffer to allow more visibility to pedestrians potentially walking out from in front of a parked bus. That will also put the cyclist in a more leftward position to be noticed
by bus drivers looking in their rear view mirrors before pulling out.
But the curb to curb width is still the same, so again I don't see a huge difference between that design and where we already ride. Of course cyclists still need to be wary of any bus with its left blinker on, as they always have.
