Tesla doesn't use Lidar, their system is actually just cameras and a prayer. It should never have been called autonomous driving, nor allowed as is.
But roadways are imperfect; Missing markers, faded paint, pedestrians, bikes, dogs, all doing unpredictable things.
We trust our autonomous Skytrain here in Vancouver, because conditions are controlled.
To apply it to air you have predefined routes and craft is forces to follow a predetermined flight plan, but centrally controlled. With a mesh net to other craft in the air.
GPS can be shifty in some areas, so there would also have station navigation, etc to guide the craft. And inter craft checking to get a mastered location.
As for falling out of the sky due to failure, yes, that's a huge problem LOL
And what are the advantages over a tram ?
Not much. We already have the skytrain system here (which is a raised rail system connecting cities and intra city travel) and it also connects to the sea ferries to cross the river, and busses.
So a point to point air travel won't add a whole lot of value in my opinion.
