I'm adding ba.transportation, since we're talking about significantly
more than just the bike lanes.

The executive summary is that I asked ba.bicycles about the new bike
lanes on Bosworth and Lyell.  The lanes on Lyell are somewhat unusual in
that Lyell is one way southeast bound for autos, but there are two new
bike lanes, one in each direction.  Most parking on Lyell was removed,
and new stop signs were added on Still at Lyell.

Uh.........no comment.  ;-)

No, I'm not really a fan of waiting, especially since that intersection
is a complete mess at evening rush hour.  I can imagine drivers getting
ticked off and riding their horns at a bike ''taking their slot'' in the
combined bike/car lanes.  Given the current configuration I'd almost
certainly dismount and use the sidewalk for the half-block from Cayuga
to Alemany if there was an auto backup.

Absolutely.  Nobody said it'd be easy.  :)

My main worry with that suggestion is that eastbound traffic from
Bosworth to Lyell would take an incredibly long time to adjust to the
new stop sign, and barrel through it rather than stopping.

Does a lot of car traffic need to make that left turn?  I'm skeptical;
if you need Alemany eastbound, you're better off taking Mission to
Trumbull, and if you need Alemany southwest bound, you probably really
need either Mission (which you'd just take directly) or San Jose (which
is trickier, but you can do Bosworth->Diamond->Monterey->Circular->
Baden to San Jose).  And allowing peds and/or bikes would give bikes the
easier route while not really inconveniencing auto traffic so much, and
obviate the need to redo the islands.

My secondary concern with the suggestion is that it doesn't address
pedestrians getting almost hit in the crosswalk for the I-280 onramp.
It seems at least as important to fix that as to fix crossing Bosworth
near Lyell.
