That's "the promise", yes, but delivering stuff is very different to promising stuff.
Planes are way ahead of trucks in this regard and could actually fly themselves from origin to destination most of the time, but we still keep a couple of highly-trained pilots sitting there to handle the rest of the cases.
A truck can kill nearly as many people as a plane, depending on its cargo and just how badly it screws up. In more common cases, though, I'm unconvinced by software's ability to figure out the best thing to do when it's travelling down the highway at 100 km/h and it sees something unexpected dash onto the road, with a better error rate than a human brain, which can at least immediately distinguish between humans and deer.
Computers can distinguish between human and deer with 100% accuracy in microseconds. Human brains aren't even close. You might as well compare a sprinter to an F1 car.
