Yes and medic-vac helicopters also exist because they&#x27;re responding to genuine emergencies which justifies both the expense and any externalities (e.g. noise and marginal danger) associated with their flying over houses etc. to save a few minutes. Sending flocks of flying vehicles over houses to deliver cables or pizzas because people need them RIGHT NOW is not the same.<p>I do see scenarios where drones make sense but I have a lot of trouble envisioning people being fine with the skies of suburbia being filled with drones all the time.
