No, it steers around them. Remote control vehicles have been around since the 1920s and self driving vehicles have been in the works since the 1960s. Why does it surprise you that NASA chose to use that sort of technology for its rovers?
I'm not bothered about it self steering. Take a look at the terrain; the rocks and the positions of those rocks. Even someone stood there operating one of those things, couldn't steer it around those rocks.
Are you trying to make out that it simply moves along; senses a rock and takes evasive action all the time with each rock, because it would be lucky to move anywhere. It's not like it has rubber monster tyres to bump over the rocks.
Actually, it started out with all terrain tires.
Oh so it landed with its all terrain tyres then pulled int at a martian station did it?
And what did the martians do?...did they do a quick tyre change like formula one or did they decide that a set of aluminium ones would do the trick.
I'm fully expecting that mouse to walk into a sheriff's office, hands up and shouting, " it's a fair cop; I'm the one in the fake mars pic. I was promised some bacon rind and a decent cube of cheese to hide away but I decided to blow the whistle."
I expect that poor mouse is still in jail or fed to some snake or pinned to a post in the desert to warn other mice to stay away from filming.
