"Where on earth is "here"?"
anywhere that is not "there".
Typical scenario on a typical city street "here" with four lanes going in each direction:
An emergency coming up from behind with horns/sirens/farts aloud, sounding like Toad in his stolen car, approaching a long queue of stationary vehicles waiting to cross another typical 8 land city street.
What to do? Convention has it that the stationary vehicles waiting at the lights DO NOT THEN PROCEED INTO THE CROSS STREETS MASSED WITH FAST VEHICLES AND CAUSE ADDITIONAL NEED FOR THE SAID EMERGENCY VEHICLE(S) TO REQUIRE TO STOP AND RENDER AID. What we tend to do then is to wait. The emergency vehicle then usually approaches the shortest queue, comes up behind, blasts everything he has which alerts the crossing traffic ahead, that he is there alerting them to stop thus allowing the queue of vehicles to slowly drive across the now stationary crossing stream of vehicles.
And it works, actually. Although, probably for the typical bloody minded Brit, it wouldn't.
People 'here" are much more tolerant.
