Moving a 20-pound chunk of metal at 20 mph with a 100-200 squishy on top amidst a bunch of unsuspecting and unexpecting other squishies may be less than maximally safe for all squishies involved. We're talking about 40-some-odd times more kinetic energy than your average squishy walking at 3 mph.
If you're forced to move into pedestrian space for safety from giant metal cages, the safest option is to actually become a pedestrian. For you and for the other squishies around. I understand that it's slow, uncomfortable, and an unpleasant cycling experience. I appreciate the sacrifice you make for the safety of your fellow squishies.
I'd also be happier with Bay biking culture if it didn't consistently make excuses for douchey cyclists.
