"Easier" is probably the right one-word generalization, but worth noting that there are quite different challenges. Stopping distance is substantially greater, so "dead halt" isn't as much of a panacea as it is in dense city environments. And you need to have good perception of things further away, especially in front of you, which affects the sensors you use.
Also on surface roads you can basically stop in the middle of the street and be annoying but not particularly dangerous. You can’t just stop safely dead in the middle of a freeway.
