The Garmin safe return is an emergency tool based on existing technology , I have no doubt that a more advanced version that will include vacating the runway , taxi and parking is not far away , however certifying an emergency tool is far easier that a standard feature with paying pax on the back . I am rather a believer that the future will be on Single man ops augmented with full automation and a man on the ground supervising the whole thing for more aircraft .
Time will tell, the Covid crisis might accelerate or delay the whole thing depending on which side of the fence the power will be.
