A rolling stop is only good enough to prevent a 'high-speed collision' as judged by people wearing steel armor boxes.
I think we can agree that 4mph is not high speed.
But I'm with you: Stop means stop
Further my habit of actually stopping has gotten me rear ended and tossed into an intersection. Doing things unexpected can be very hazardous.
It's a shame that following signs is unexpected. Somehow, it's not acceptable to run a red light because "no-one is around anyway", but it's fine to do rolling stops?
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.
