> Surely you don't intend to imply that the horse is ordering. Haha no (should have explained), but riders are too high to be heard due to the directional microphones installed and you only effectively hear the horse. Same for very high seated cars (though I suspect this might be different in the US). Trucks are too tall and would hit the building so they are not a consideration for the one I worked at. As you said, a simple alert system might work to solve this.
