There is at least one state (Idaho [1]) in the US where cyclists are legally allowed to treat a stop sign like a yield sign.

This doesn't happen, at least from my limited experience in Beverly Hills.

I ride several blocks to work sometimes and I take local streets which all have 4 ways stop signs.

9 out of 10 cars yield and refuse to go. I get the pedestrian treatment.
