Your mom’s what??

Certainly around my area in a UK city there are plenty which automatically go to a green man even if no button was pressed. This is usually the case on more complicated intersections where in order to keep traffic flowing correctly that pedestrian crossing would be free at some point anyway, so they just put the green man cycle on by default. Of course they still put a button for pedestrian-satisfying reasons!

Sorry to be that guy but it’s actually just in regular ionian mode! If it was mixolydian the first note of the ‘insert name’ part of the tune would be flattened.
