There is no actual evidence that drones were involved in any of these near miss incidents! All based on what pilots thought they saw. Just to put it in perspective a phantom is half the height of a letter on a motorway sign, with no contrasting background and at 3+ times the speed of motorway driving. So not only are these accounts of identifying one unlikely but drones do not fly at 200mph, so at least 2 of them would have simply been physically impossible.
Planes are tested and completely destroy metal debris of 13kg, a 0.5kg plastic drone realistically poses no threat whatsoever.
And importantly IF these were drones, they were already flying illegally, no additional restrictions are neccesary because they were already breaking the existing ones.
PS. GPS restrictions are much easier to say than apply. In practice they actually increase the danger and risk of flyaways and out of control drones. Some drones try to do this already and has caused numerous problems with false positives and flyaways. Also a lot of drones do not have a high level or any GPS functionality. So this is not a good solution.
