They are trying to 'balance' it. First they came up with stupid PA training, now this. Making PA in some sort of a vehicle is actually not a bad idea though.
They could go the way of Van Buren and simply have Power Armor require a code.
Want to activate Power Armor? You need a code for the armor's systems to work. Otherwise, it doesn't work, or you're stuck with a gyro-less, non-exoesqueleton Power Armor (AKA NCR "Power Armor", used by the NCR Heavy Troopers) that is essentially super bullet-proof plate armor. It makes a lot more sense that FNV's Heavy Troopers wore a mix of scavenged suits (with no gyros and exoesqueleton, just armor) and suits that had their gyros and exoesqueletons taken out because of lack of code, rather than simply stripping the good stuff out because "lol we can't use it because we have no training or manual and nobody can simply wing it then train others".
