I'm getting the idea, I believe.
It's beginning to seem to me that these things aren't quite as "frisky" as one might think if we did compare it to a golf cart, for instance. We may have assumed some traits which aren't there.
They seem to be very good at what they do, but unstable, maneuverable but with difficulty, slow, and power-hungry in a limited-power environment.
And with a limited life. That isn't to say they can't do what they do, just that it may not be as easy or fast as we may have thought.
Taking a picture of part of the lander might not be as feasible as it seems.
