Heart rate and power (in watts) are used as a measure of how hard you’re going. During intervals you’re almost always trying to target a specific heart rate zone and stay there. During long climbs, elite riders know how many watts they’re capable of making and for how long. Watts then become a way to pace yourself and avoid going too hard. Same with heart rate

If the usage is meant in the city where as you mentioned the focus is on avoiding all kinds of obstacles, having the heart rate occupying display estate is at best meaningless and at worst dangerous.
