Hindrances Regulations: The major problem that might hinder the use of drone for deliveries is regulation. The FAA has yet to come up with a complete handbook on laws and regulations pertaining to drones and delivery services.
Weight: The second issue is weight. It is evident that drones would not be able to carry large amounts of packages. Amazon’s Prime Air weighs about 55 lbs while Google’s drone is a mere 19 lbs. So, they would be carrying weights less than their weight.
