True. I'm sure some safeguards could have been put in-place using existing data. Similar to simultaneous location and mapping. But as I said, the design of aviation systems is surprisingly stupid. They have TCAS warning and know the height of the ground at any point on earth. Yet they'll let you dial up a path on the autopilot that flies straight through a mountain. It's only relatively recently that light aircraft autopilots gained envelop protection, until then they'd happily fly an aircraft into a stall trying to maintain the set parameters.
