0d (parked) - null program easy

1d (train) - easy. just one lever

2d (car) - hard. super hard. why is it so crowded? who thought this was a good idea? you let teenagers do this?

2.5d (plane at takeoff or landing) - almost as hard as car. fewer pedestrians.

3d (plane flying) - easy even with all those extra levers

I'm not actually sure how hard landing is. Most airports that support autonomous landings do it by having ILS antennae that guide the airplane to within tens of feet of the runway, at which point the airplane switches to radar for altitude.

Automatic landings started in 1964. I think that it seems hard mostly because of how tightly regulated aviation is - modern technology could probably make things a lot better if people were more receptive to the idea of heavy automated aircraft over populated areas.

landing is easy. the hard part is landing with 20mph cross winds and one engine out (or other mechanical failures). we've had auto-land that is 99% reliable for a while now, but you need to get to 6 9s before you have a system safe enough to replace pilots

1d, variant (tram) - hard, who thought it was a good idea to send rail-bound vehicles and steerable vehicles down the same road?

3d, variant (orbital) - super hard, so hard that trajectory pre-calculations has to be performed
