Other that being incorrect on all your factual premise, you're also rather unreasoned in your view of driver information.
FYI, :
"British European Airways ordered a fleet of Hawker Siddeley HS 121 Tridents, three-engine jetliners that in 1965 became the first transports to fly automatic landings in revenue service."

Presently some version of autoland is available even on small aircraft:
The FAA on May 15 certified Garmin Autoland on the Piper M600/SLS, making it the first airplane ever certified with a system that will land the airplane on its own should the pilot become incapacitated.

Not only do aircraft have autoland they also have ground auto navigation coming:
Airbus has launched a new series of Ground Control Points (GCPs) to give centimetre level accuracy and higher points density. These highly precise 3D coordinates are automatically extracted from Airbus’ high-resolution stereo radar imagery, using an innovative geodesy processor.

As for the 1500 feet nonsense that has not been true ever. There could be, perhaps, some use of such limits somewhere. unlikely but possible somewhere for some operations, most likely training ones. In normal practice for IFR, pilots tend to choose autopilot until minimum approach height, unless using autoland. That is tendency, not regulatory.
Although I'm a former Airline Transport Pilot and CFI I am not current. The data, though, is readily accessible.
As we consider automotive use of driving aids and eventually true point-to-point automation, you're woefully out of touch with present reality, including Tesla and several others.
Just as even small Cessnas have excellent autopilots available today, we might understand that "hand flying" today is now mostly for sport. Very soon, "hand driving" will be thus. As with aircraft automated systems, none of the ones for vehicles anytime soon are able to be 100% supervised. Even fully automatic aircraft still have monitoring and remote control in some respect. So it will be for vehicles for some time, probably including Robotaxi at least when it begins.
