I think a lot of people here are confusing a 'rolling stop' with 'blowing a stop sign'.

The former you slow down significantly and check both directions (generally a 4 way stop sign). If you can see that no other car is going to get there before you, you would have the right of way anyway. So instead of coming to a complete stop then starting again you roll through the sign.

I feel I have to explain this since everyone has imprinted the image of a cyclist ignoring traffic and blowing through streets in there head.
