I hear this a lot, along with comments about self-driving cars being unusable because 'people will run in front of them to make them stop', and I just don't get it. In what country would it be deemed legal and normal for people to shoot down drones? Do people take pot-shots at light aircraft? Why would people suddenly want to shhot at drones? The same with self-driving cars - people don't run into traffic to make human drivers stop, although they would certainly try their best not to run you over, so why would they start doing it with self-driving cars. I've also heard the argument that people will vandalise the cars, destroy the LIDAR sensors and so on, but yet we don't have spates of people throwinf paint over the windscreen of normal cars. I think it says more about the mentality of the commentors that about the peeibilities for automated vehicles, flying or driving.
