Responding to each of ur answer
1) added height does not produce further sight as it varies with the height of that person.
2) depending on the location of the emergency; which floor, if it's three levels down, I don't think riding that thjnf would be faster
3) I am still thinking about that one

1. they can see farther when patrolling because of the added height...
2. they can respond more quickly to any emergency situation..
3. they can cover more areas than by foot patrol within the same period of time.
