Blind intersection, with or without traffic signs -- I always stop or very nearly so

Clear view across the intersection on quiet roads, no other traffic -- not likely, though I might slow a bit

Clear view across the intersection on busy roads -- slow down to double-check, and maybe stop

When riding with other vehicles in traffic (i.e. moving with me in the same direction) -- even if I can see the cross-intersection is clear, I will stop if I'm going straight across and wait for the light. If I'm going right, I will slow down and do a slow-roll "right on red." Complete stop, of course, if there is cross traffic.

My biggest issue is I'm still new to clipless pedals, so coming to a dead stop is still not 100% comfortable, and neither is clipping back in. If I can keep going to avoid clipping out/in, I'll do that, but not in a way that will cause a car to have to guess at what I'm doing.

-- I think this might also have to do with the larger cultural context. In the Boston area, there are a lot of bikers, and car drivers don't generally obey traffic laws. The old "Boston stop sign" where the stop at the sign of the first car applies to the next 3-4 cars (so they all roll through together). That's faded somewhat here, but it was a huge part of Boston for a long time, and some of it is still around.
